Sustained exposure to hypoxia has adverse effects on body weight, muscle structure and exercise capacity, mental This article examines the various parts of the respiratory system, some respiratory conditions, and how a person breathes. Function: 1: nose: A nose is a nose is a nose. Within this hollow space, the air is warmed, moisturized, and filtered before reaching the lungs. An Experimental Human Colonization Model with Pneumococcal Serotype 3 has the Potential to be Used for Vaccine Studies. The causes of these issues are just as variedamong them, infection (bacterial or viral), environmental exposure (pollution or cigarette smoke, for instance), genetic inheritance or a combination of factors. They require different treatments, which will depend on how far the condition has progressed. Omissions? It is made up of several organs and structures that transport air into and out of the lungs, exchanging oxygen with carbon dioxide. People who smoke heavily may experience inflammation of the airways, which makes it difficult for the lungs to inhale and exhale enough air. The paranasal (meaning around the nose) sinuses are four paired, hollow spaces above and below the eyes. The size, location, mucous lining and tiny hairs (cilia) inside help prevent foreign objects to enter and to trap large air impurities before being drawn further into the respiratory system. Between the ribs are many small intercostal muscles that assist the diaphragm with expanding and compressing the lungs. The duct drains the lacrimal fluid into the nasal cavity. The process of digestion has three stages: the cephalic phase, the to bring oxygen to the body.

In addition, the respiratory system plays an important role in thermoregulation (maintaining normal body temperature). The left lung is therefore slightly smaller than the right lung and is made up of 2 lobes while the right lung has 3 lobes. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. At the inferior end of the trachea, the airway splits into left and right branches known as the primary bronchi. This page will serve as a hub for all COVID-19 related manuscripts published across all four ATS Journals. The nasal cavity is the uppermost part of the respiratory system, divided into two by the nasal septum. The nasopharynx is the superior region of the pharynx found in the posterior of the nasal cavity. Supplements for heart health: Which ones are beneficial and which ones are not? Please select which sections you would like to print: Overview mechanism and anatomy of the respiratory tract; passaging air from the mouth and nose to the lungs. The avian respiratory system is involved in the following functions: First by outlining the lungs, bronchi, and trachea, then detailing additional components and accessory structures. The pharynx is divided into 3 regions: the nasopharynx, oropharynx, and laryngopharynx. While every effort has been made to follow citation style rules, there may be some discrepancies. Respiratory structures include the nasal passages, trachea, lungs, and diaphragm. Your injury might make it more difficult to breathe and cough if your abdominal and chest muscles are affected. The respiratory system uses both a negative pressure system and the contraction of muscles to achieve pulmonary ventilation. The respiratory system does this through breathing. This keeps the passage to the esophagus covered, preventing air from entering the digestive system. A similar exchange of gases takes place at body tissues and cells. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. Respiratory syncytial virus (RSV) infection and human metapneumovirus infection (hMVP) cause upper and sometimes lower respiratory tract infections. The one advantage of breathing through the mouth is that its shorter distance and larger diameter allows more air to quickly enter the body. To do this, at least four distinct events, collectively called respiration, must occur. Let's take a tour of the lungs! Other types of upper respiratory tract infections include sinusitis (inflammation of the sinuses), tonsillitis (inflammation of the tonsils), epiglottitis (inflammation of the epiglottis that covers the trachea), laryngitis (inflammation of the larynx) and influenza. This page will serve as a hub for all COVID-19 related manuscripts published across all four ATS Journals. By continuing to browse Respiratory care. This exchange of gases is the respiratory system's means of getting oxygen to the blood. Diseases of the pleural cavity (the potential space between the lungs and chest wall) can also affect the function of the respiratory system. The respiratory system's primary function is to supply oxygen to all the parts of your body. There is no need to contact the Editor-in-Chief or Publications Office in advance. The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs.In vertebrates, the hypothalamus is the neural control center for all endocrine systems. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. Your respiratory system has built-in methods to keep harmful things in the air from entering your lungs. "Respiratory System and How We Breathe." In addition, the epithelium lining the trachea produces mucus that traps dust and other contaminants and prevents it from reaching the lungs. Your body has about 600 million alveoli. Pass out copies of our lesson Respiratory System: Function & Physiology. Bacteria and viruses can infect the respiratory system and cause disease. At the same time, carbon dioxide diffuses from the blood into the alveoli sacs and is exhaled through air passages. Your neurological level of injury will determine what kind of breathing problems you have. Let us know if you have suggestions to improve this article (requires login). Among other medications, doctors may prescribe inhalers containing corticosteroids to treat this condition. The diaphragm separates the chest and abdominal cavities. Knowledge of the avian respiratory system is essential for developing a health monitoring plan for a poultry flock, recognizing problems that may occur, and taking action to correct them. Reduced respiratory system compliance; Elevated ratio of dead space to tidal volume; Tachypnoea; Hypoxaemia; Diaphragm breathing - disease related changes to the mechanics of breathing can lead to a reduction in diaphragm mobility.

There are a number of facets involved in breathing. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The pharynx, or throat, is a versatile muscular tube, shaped like a funnel, that delivers air from the mouth and nose to the trachea, or windpipe. A symptom of bronchitis is an inflammation of the lung airways. The larynx is a 2-inch tube made up of nine cartilage pieces. Sensors in air passages detect the presence of irritants such as smoke, pollen, or water. Structures of the respiratory system can be grouped into three main categories: air passages, pulmonary vessels, and respiratory muscles. Air exiting the body through the nose returns moisture and heat to the nasal cavity before being exhaled into the environment. These cookies track visitors across websites and collect information to provide customized ads. The respiratory system in human beings can be divided into the upper respiratory tract that consists of nasal passages, pharynx, and larynx, and the lower respiratory tract that is composed of the trachea, the primary bronchi, and the lungs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. These arteries form smaller blood vessels called arterioles which send blood tocapillaries surrounding millions of lung alveoli. After absorbing oxygen, blood goes to yourheart. Its components are a group of muscles, blood vessels, and organs. The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. answer choices . Learn about its causes, Medical News Today has strict sourcing guidelines and draws only from peer-reviewed studies, academic research institutions, and medical journals and associations. When we breathe, we inhale oxygen and exhale carbon dioxide. Learn more about the trachea here. The respiratory system is the organ system that enables us to breathe. There are two types of lung cancer: small cell and non-small cell lung cancer. The exchange of oxygen and carbon dioxide occurs before exhalation. Carbonic acid then dissociates into hydrogen ion and bicarbonate ion. Retrieved from https://www.thoughtco.com/respiratory-system-4064891. The respiratory system is divided into an upper and lower respiratory tract. human respiratory system, the system in humans that takes up oxygen and expels carbon dioxide. The major structures of the respiratory system function primarily to provide oxygen to body tissues for cellular respiration, remove the waste product carbon dioxide, and help to maintain acid-base balance. The intrapulmonary conducting airways: bronchi and bronchioles, Blood vessels, lymphatic vessels, and nerves, Central organization of respiratory neurons, Interplay of respiration, circulation, and metabolism, https://www.britannica.com/science/human-respiratory-system, University of Michigan - The Mechanism of Human Respiration in Detail, Kids Health - For Parents - Lungs and Respiratory System, Biology LibreTexts - Structure and Function of the Respiratory System, MSD Manual - Consumer Version - Overview of the Respiratory System, respiratory system - Children's Encyclopedia (Ages 8-11), respiratory system - Student Encyclopedia (Ages 11 and up). High-altitude (HA) environments have adverse effects on the normal functioning body of people accustomed to living at low altitudes because of the change in barometric pressure which causes decrease in the amount of oxygen leading to hypobaric hypoxia. Relaxation of the diaphragm allows air to flow back out the lungs during exhalation. High-altitude (HA) environments have adverse effects on the normal functioning body of people accustomed to living at low altitudes because of the change in barometric pressure which causes decrease in the amount of oxygen leading to hypobaric hypoxia. The passageways thus formed below each ridge are called the superior, middle, and inferior nasal meatuses. Learn, Respiratory depression, or hypoventilation, is when the lungs do not exchange gases properly, causing a low breathing rate. Your injury might make it more difficult to breathe and cough if your abdominal and chest muscles are affected. Bronchitis (inflammation of the bronchial tubes), pneumonia (inflammation of the lung alveoli), tuberculosis, and influenza are types of lower respiratory tract infections. The respiratory system does this through breathing. Hemoglobin is an important transport molecule found in red blood cells that carries almost 99% of the oxygen in the blood. ThoughtCo. The avian respiratory system is involved in the following functions: 2004-2022 Healthline Media UK Ltd, Brighton, UK, a Red Ventures Company. Once the lungs expand, air moves in through the nose and mouth. Some of the bones and muscles in the respiratory system include your: Diaphragm: Muscle that helps your lungs pull in air and push it out. Spirograms can be indicative of certain respiratory disorders or of healthy lung function. Surrounding the lungs are sets of muscles that are able to cause air to be inhaled or exhaled from the lungs. For respiration, the collaboration of other organ systems is clearly essential. Cells in your trachea and bronchial tubes make mucus that keeps air passages moist and helps keep things like dust, bacteria and viruses, andallergy-causing things out of your lungs. The mouth, also known as the oral cavity, is the secondary external opening for the respiratory tract. The major muscle of respiration is a sheet-like dome shaped muscle called the diaphragm that is located below the lungs. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. As the diaphragm contracts, it flattens out, moving toward the abdominal cavity. Blood plasma has the ability to transport some dissolved oxygen and carbon dioxide, but most of the gases transported in the blood are bonded to transport molecules. Atmospheric air is pumped in and out regularly through a system of pipes, called conducting airways, which join the gas-exchange region with the outside of the body. Function What does the respiratory system do? All Rights Reserved. The lower airway system consists of the larynx, the trachea, the stem bronchi, and all the airways ramifying intensively within the lungs, such as the intrapulmonary bronchi, the bronchioles, and the alveolar ducts. To do this, at least four distinct events, collectively called respiration, must occur. Achooo! The lungs are the primary organs of the respiratory system, as they perform a vital role in breathing: gas exchange. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the bodys exterior. However, when the muscle contracts, it pulls downward, adding size to the thoracic cavity. The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Chronic bronchitis is a form of COPD. Respiratory diseases are the most common cause of death in a poultry flock. The process of breathing is under the direction of the peripheral nervous system (PNS). On average, people breathe 1020 times per minute. It is the best entrance for outside air, as hairs and mucus line the inside wall and operate as air cleansers. These actions, however, can be overridden by the autonomic nervous system. It also receives waste Carbon Dioxide from the blood and exhales it. Copyright 1987-2022 American Thoracic Society, All Rights Reserved. When you breathe in, your diaphragm pulls downward, creating a vacuum that causes a rush of air into your lungs. The function of the human respiratory system is to transport air into the lungs and facilitate the diffusion of oxygen into the bloodstream. However, the lungs also take the carbon dioxide from the blood and release it into the air when a person breathes out. It connects the pharynx with the trachea and is held together by ligaments, membranes, and fibrous tissue. The paranasal sinuses are sets of paired single or multiple cavities of variable size. Typically, the mucosa of the nose contains mucus-secreting glands and venous plexuses; its top cell layer, the epithelium, consists principally of two cell types, ciliated and secreting cells. When the partial pressure of carbon dioxide is high in the tissues, the enzyme carbonic anhydrase catalyzes a reaction between carbon dioxide and water to form carbonic acid. The human gas-exchanging organ, the lung, is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage. Function: 1: nose: A nose is a nose is a nose. The alveoli are lined with thin simple squamous epithelium that allows air entering the alveoli to exchange its gases with the blood passing through the capillaries. MNT is the registered trade mark of Healthline Media. The nose prevents dust, mold, and other contaminants from reaching the lungs. First by outlining the lungs, bronchi, and trachea, then detailing additional components and accessory structures. At this point, more air can be inhaled by the contraction of the diaphragm and the external intercostal muscles, increasing the volume of the thorax and reducing the pressure of the lungs below that of the atmosphere again. The cells of the human body require a constant stream of oxygen to stay alive. With so many working parts, keeping the respiratory system healthy is important. Her work has been featured in "Kaplan AP Biology" and "The Internet for Cellular and Molecular Biologists.". Diaphragm muscle ; Curriculum Standards. Connected to the nose by small openings, they regulate the temperature and humidity of inhaled air. The cookies is used to store the user consent for the cookies in the category "Necessary". Information from these sets of sensors is sent to the respiratory center which activates the effector organs the diaphragm and other muscles of respiration. This distinction is important because the diaphragm is located below the lungs and occupies this space. Function What does the respiratory system do? What is the main function of the respiratory system? The trachea is a tube-like passage that runs down the neck and upper chest, carrying air to and from the lungs. The airways can be divided into upper and lower airway systems. The lungs are the centerpiece of your respiratory system. Tiny hairs, called cilia, along your air passages move in a sweeping motion to keep the passages clean. These structures are typically grouped into three main categories: air passages, pulmonary vessels, and respiratory muscles. As the muscles that assist in breathing get weaker, the bronchial system must be kept free of secretions, either by using a cough assist device or by manual assisted coughing with the help of a caregiver. The cells of the human body require a constant stream of oxygen to stay alive. Gases are also exchanged between the blood and body cells. Breathing starts when you inhale air into your nose ormouth. The alveoli are cup-shaped structures found at the end of the terminal bronchioles and surrounded by capillaries. It is subdivided into a left and right canal by a thin medial cartilaginous and bony wall, the nasal septum. Spirograms can be indicative of certain respiratory disorders or of healthy lung function. This cookie is set by GDPR Cookie Consent plugin. The bronchioles differ from the structure of the bronchi in that they do not contain any cartilage at all. The following sections will look at some respiratory conditions in more detail. As the muscles that assist in breathing get weaker, the bronchial system must be kept free of secretions, either by using a cough assist device or by manual assisted coughing with the help of a caregiver. The function of the human respiratory system is to transport air into the lungs and facilitate the diffusion of oxygen into the bloodstream. Beneath the lungs is the diaphragm (say: DY-uh-fram), a dome-shaped muscle that works with your lungs to allow you to inhale (breathe in) and exhale (breathe out) air. Diaphragm. Most of their development takes place after birth, and they reach their final size toward age 20. Innerbody Research is the largest home health and wellness guide online, helping over one million visitors each month learn about health products and services. The difference in partial pressures leads to the diffusion of gases along their pressure gradients from high to low pressure through the endothelium lining of the capillaries. to bring oxygen to the body. There are two phases of breathing: in and out. COVID-19 is a new form of Coronavirus disease due to the novel virus SARS-CoV2 that causes acute infection with respiratory symptoms. The lung provides the tissues of the human body with a continuous flow of oxygen and clears the blood of the For yourlungsto perform their best, these airways need to be open. The primary function of this system is to provide body tissues and cells with life-giving oxygen while expelling carbon dioxide. The two main types of bronchitis are acute and chronic. Last medically reviewed on July 29, 2020, The lungs are self-cleaning organs, but people can also use certain methods to clear mucus and open up the airways. Hypertension: Can 15 minutes of yoga a day help control blood pressure? Mike is creator & CEO of TeachPE.com. If you have a cervical and thoracic spinal cord injury, you might have an increased risk of pneumonia or other lung problems. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. Due to the complex nature of the respiratory system, many health conditions can affect it. Inhalation and exhalation are how your body brings in oxygen and gets rid of carbon dioxide. People can do this by avoiding smoking, eating a healthful diet, and exercising regularly. The grape-like sacs called alveoli in each lung allow the exchange of oxygen and carbon dioxide to take place. The diaphragm is shaped like a dome and is at its maximum height when it is relaxed. The principal muscle of respiration in the human body is the diaphragm, a thin sheet of skeletal muscle that forms the floor of the thorax. Respiratory system. The function of the human respiratory system is to transport air into the lungs and facilitate the diffusion of oxygen into the bloodstream. Dyspnea. The respiratory centers in the medulla control breathing rate and can speed up or slow down the process when needed. Pulmonary arteries transport oxygen-depleted blood containing carbon dioxide to the lungs. WebMD does not provide medical advice, diagnosis or treatment. Spirograms can be indicative of certain respiratory disorders or of healthy lung function. Your lungs work with your respiratory system to allow you to take in fresh air, get rid of stale air, and even talk. Symptoms of both viruses are similar although the viruses are different. The larynx has a dual function in the respiratory system: as an air canal to the lungs (while stopping food and drink from blocking the airway) and as the voice box (which contains vocal cords for speech). They may also recommend hospitalization for serious cases. In the breathing process, air flows into and out of the lungs. Lung alveoli are coated with a moist film that dissolves air. High-flow Nasal Cannula Oxygen Therapy for Stable Hypercapnic COPD: Just Good Enough? Because the pathway of air entering the body from the mouth is shorter than the pathway for air entering from the nose, the mouth does not warm and moisturize the air entering the lungs as well as the nose performs this function. Internal respiration is the exchange of gases between the blood in capillaries and the tissues of the body. answer choices . ThoughtCo, Aug. 26, 2020, thoughtco.com/respiratory-system-4064891. 2005 - 2022 WebMD LLC. Neurons in the medulla send signals to the diaphragm and the intercostal muscles to regulate the contractions which initiate the breathing process. The contribution of the lung and chest wall (ribs and muscles) to respiration is described below in The mechanics of breathing. Smelling, tasting and breathing all start here. The human gas-exchanging organ, the lung, is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage. Your respiratory system also includes the trachea (windpipe), muscles of the chest wall and diaphragm, blood vessels, and other tissues. Finally, the millions of tiny terminal bronchioles conduct air to the alveoli of the lungs. Examples of respiratory structures include the nose, mouth, lungs, and diaphragm. The lungs are the centerpiece of your respiratory system. Knowledge of the avian respiratory system is essential for developing a health monitoring plan for a poultry flock, recognizing problems that may occur, and taking action to correct them. Bailey, Regina. The diaphragm is a dome-shaped sheet of muscle located below the lungs. Your neurological level of injury will determine what kind of breathing problems you have. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. The smooth muscle fibers are able to contract during rest to prevent hyperventilation. The primary function of this system is to provide body tissues and cells with life-giving oxygen while expelling carbon dioxide.

Pass out copies of our lesson Respiratory System: Function & Physiology. Normally there is only a tiny amount of fluid in this space, and the fluid serves to lubricate the lungs and to decrease friction between the lungs, the rib cage, and diaphragm. Respiratory system. Diaphragm. Symptoms include a high temperature, a cough, difficulty breathing, and chest pain. Oxygen enters the lungs, then the bloodstream, allowing the body to function normally. Autonomic chemoreceptors in the body monitor the partial pressures of oxygen and carbon dioxide in the blood and send signals to the respiratory center of the brain stem. Articles from Britannica Encyclopedias for elementary and high school students. These gases are transported via thebloodto sites of gas exchange (lungsand cells) by thecirculatory system. All submissions must be evaluated by the editors and we cannot guarantee publication. The lung provides the tissues of the human body with a continuous flow of oxygen and clears the blood of the gaseous waste product, carbon dioxide. This Bodytomy article tells you about the human respiratory system structure with the help of diagrams. The oxygen-rich blood is then transported to the heart where it is pumped out to the rest of the body. Oxygen (which. Dyspnea. The secondary bronchi carry air into the lobes of the lungs2 in the left lung and 3 in the right lung. Go inside the human body and see first-hand how the respiratory system works. But opting out of some of these cookies may affect your browsing experience. In this article, we look at seven. Most normal breathing takes place through the nasal cavity, but the oral cavity can be used to supplement or replace the nasal cavitys functions when needed. This results in air following the pressure gradient and passively filling the lungs at rest.

During expiration through the nose, the air is dried and cooled, a process that saves water and energy. To exhale air, the diaphragm and external intercostal muscles relax while the internal intercostal muscles contract to reduce the volume of the thorax and increase the pressure within the thoracic cavity. The Respiratory system is controlled in mammals by the diaphragm muscle. Respiratory diseases are the most common cause of death in a poultry flock. Each canal opens to the face by a nostril and into the pharynx by the choana. All COVID-19 content will be reviewed expeditiously. When the diaphragm relaxes, the thoracic cavity decreases in size. A respiratory therapist or pulmonologist can be consulted for the needed information. Muscles in the ribs also help enlarge the chest cavity, pulling the rib cage upward and outward.

The avian respiratory system delivers oxygen from the air to the tissues and also removes carbon dioxide. Reduced respiratory system compliance; Elevated ratio of dead space to tidal volume; Tachypnoea; Hypoxaemia; Diaphragm breathing - disease related changes to the mechanics of breathing can lead to a reduction in diaphragm mobility. It accomplishes this through breathing: inhaling oxygen-rich air and exhaling air filled with carbon dioxide, which is a waste gas. Your lungs work with your respiratory system to allow you to take in fresh air, get rid of stale air, and even talk. The inhaled air then descends into the laryngopharynx, where it is diverted into the opening of the larynx by the epiglottis. Lung cancer begins in the lungs but may spread to the lymph nodes or other areas of the body. The lung provides the tissues of the human body with a continuous flow of oxygen and clears the blood of the Your respiratory system also includes the trachea (windpipe), muscles of the chest wall and diaphragm, blood vessels, and other tissues. The respiratory system is the organs and other parts of your body involved in breathing, when you exchange oxygen and carbon dioxide. This page will serve as a hub for all COVID-19 related manuscripts published across all four ATS Journals. The muscles expand and contract the internal space of the thorax, the bony framework of which is formed by the ribs and the thoracic vertebrae. The primary function of this system is to provide body tissues and cells with life-giving oxygen while expelling carbon dioxide. The lungs are a pair of large, spongy organs found in the thorax lateral to the heart and superior to the diaphragm. You can learn more about how we ensure our content is accurate and current by reading our. Inhaled air from the nasal cavity passes into the nasopharynx and descends through the oropharynx, located in the posterior of the oral cavity. When you breathe in, the diaphragm moves downward toward the abdomen, and the 2: mouth* This exchange of gases is the respiratory system's means of getting oxygen to the blood. In which of the following ages groups is RSV a very common cause of respiratory tract infections? Corrections? Updates? Hemoglobin can also carry a small amount of carbon dioxide from the tissues back to the lungs. We avoid using tertiary references. Sinusitis can cause inflammation of the air cavities within the nose and lead to facial pain, headache, and a blocked or runny nose. About two dozen olfactory nerves convey the sensation of smell from the olfactory cells through the bony roof of the nasal cavity to the central nervous system.

These two nerves regulate the activity of the respiratory muscles, the diaphragm, and external intercostals. the site you are agreeing to our use of cookies. The major function of the respiratory system is to supply the body with oxygen and to dispose of carbon dioxide. Under normal resting conditions, the body maintains a quiet breathing rate and depth called eupnea. This can lead to health problems likebronchitis. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. Hairs in your nose help filter out large particles. In addition to breathing, the respiratory system also assists in vocalization and the sense of smell. The net result of internal respiration is the diffusion of oxygen into the tissues and the diffusion of carbon dioxide into the blood. The diaphragm operates as the major muscle of respiration and aids breathing. The cells of the human body require a constant stream of oxygen to stay alive.

Respiratory structures sometimes come in contact with infectious agents like bacteria and viruses. What is the main function of the respiratory system? The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs.In vertebrates, the hypothalamus is the neural control center for all endocrine systems. Mucus can bring up things that reach deeper into your lungs. As the cells use the oxygen, they make carbon dioxide that goes into your blood. The complex shape of the nasal cavity is due to projections of bony ridges, the superior, middle, and inferior turbinate bones (or conchae), from the lateral wall. The trachea, or windpipe, is a 5-inch long tube made of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium. The major function of the respiratory system is to supply the body with oxygen and to dispose of carbon dioxide. It also receives waste Carbon Dioxide from the blood and exhales it. The negative pressure system of the respiratory system involves the establishment of a negative pressure gradient between the alveoli and the external atmosphere. The interior of the lungs is made up of spongy tissues containing many capillaries and around 30 million tiny sacs known as alveoli. The human gas-exchanging organ, the lung, is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage.
