Arteries are muscular and elastic-walled vessels that form a network to carry oxygen-rich blood from the heart to all parts of the body. Smaller branches called arterioles extend from the arteries and connect to even smaller branches called metarterioles which deliver the blood to the capillaries. The exchange of oxygen and carbon dioxide between blood and body cells takes place through the thin walls of the capillaries.
There are two principal arteries or arterial trunks: the aorta, which rises from the left ventricle of the heart and ramifies through the whole body, sending off great branches to the head, neck, and upper limbs, and downwards to the lower limbs, etc; and the pulmonary artery, which conveys venous blood from the right ventricle to the lungs, to be purified in the process of respiration.
