When oxygen delivery is insufficient to support tissue metabolic requirements, a person is said to be in circulatory shock. The precapillary sphincters, circular smooth muscle cells that surround the capillary at its origin with the metarteriole, tightly regulate the flow of blood from a metarteriole to the capillaries it supplies. Their abundant elastic fibres allow them to expand as blood pumped from the ventricles passes through them, and then to recoil after the surge has passed. An arteriole is a very small artery that leads to a capillary. WebFoot, leg, and ankle swelling is common when the person also: Is overweight; Has a blood clot in the leg; Is older; Has a leg infection; Has veins in the legs that cannot properly pump blood back to the heart (called venous insufficiency, most often due to varicose veins); Injury or surgery involving the leg, ankle, or foot can also cause swelling.
