arteries form part of the circulatory system. they carry blood that is oxygenated after it has been pumped from the heart. coronary arteries also aid the heart in pumping blood by sending oxygenated blood to the heart, allowing the muscles to function. arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation (usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood as well). there are two types of unique arteries. the pulmonary artery carries blood from the heart to the lungs, where it receives oxygen. it is unique because the blood in it is not "oxygenated", as it has not yet passed through the lungs. the other unique artery is the umbilical artery, which carries deoxygenated blood from a fetus to its mother.

the veins of the arm carry blood from the extremities of the limb, as well as drain the arm itself. the two main veins are the basilic and the cephalic veins. there is a connecting vein between the two, the median cubital vein, which passes through the cubital fossa and is clinically important for venepuncture (withdrawing blood).









































the basilic vein travels on the medial side of the arm and terminates at the level of the seventh rib.
