artery,

blood vessel that conveys blood away from the heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function

The human heart is a pear-shaped structure about the size of a fist.

. Except for the pulmonary artery, which carries deoxygenated blood from the heart to the lungs, arteries carry oxygenated blood from the heart to the tissues. The largest arterial trunk is the aortaaorta
, primary artery of the circulatory system in mammals, delivering oxygenated blood to all other arteries except those of the lungs. The human aorta, c.1 in. (2.54 cm) in diameter, originates at the left ventricle of the heart.

, microscopic blood vessel, smallest unit of the circulatory system. Capillaries form a network of tiny tubes throughout the body, connecting arterioles (smallest arteries) and venules (smallest veins).

blood vessel that returns blood to the heart. Except for the pulmonary vein, which carries oxygenated blood from the lungs to the heart, veins carry deoxygenated blood. The oxygen-depleted blood passes from the capillaries to the venules (small veins).

). Other important arteries are the subclavian and brachial arteries of the shoulder and arm, the carotid arteries that lead to the head, the coronary arteries that nourish the heart itself, and the iliac and femoral arteries of the abdomen and lower extremities. The walls of the large arteries have three layers: a tough elastic outer coat, a layer of muscular tissue, and a smooth, thin inner coat. Arterial walls expand and contract with each heartbeat, pumping blood throughout the body. The pulsating movement of blood, or pulsepulse,
alternate expansion and contraction of artery walls as heart action varies blood volume within the arteries. Artery walls are elastic. Hence they become distended by increased blood volume during systole, or contraction of the heart.

Attention was then directed to the severe stenosis of the left proximal external iliac artery. A 7 mm x 4 cm Dorado[R] (BARD Peripheral Vascular) angioplasty balloon was utilized to dilate the stenosis followed by placement of an 8 mm x 5 cm Gore Viabahn Endoprosthesis which extended from the mid left common iliac artery to the proximal external iliac artery (Figure 4).

Proximal control was gained above the infrarenal abdominal aortic aneurysm and repair of both was undertaken with bifurcated Dacron graft, anastomosed onto the left common iliac artery and the right external iliac artery, as the origin of the right common iliac artery was also aneurysmal.
It continues on the pelvic sidewall medial to the infundibulopelvic ligament as it crosses the external iliac artery. Branches of the internal iliac artery supply the descending portion of the ureter and move along the course of the ureter from the lateral aspect.
