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).

, the latter connecting with the veinsvein,
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.

In the present case the brachial artery has divided into radial artery and common interosseous artery (instead of ulnar artery) in the cubital fossa at the level of neck of radius (Photograph 2).
It is supplied by the posterior interosseous artery, which is a branch of the common interosseous artery or by the ulnar artery directly.
Transiently, the median artery arises as a branch of the interosseous artery, begins to regress and remains as a residual artery accompanying the median nerve.
A bifurcating ulnar artery yields a trunk, the common interosseous artery and the main ulnar artery which gave off the persistent median artery between the artery and caudal angle of the common interosseous artery.
This is represented by brachial and interosseous artery. Then new arteries arise by angiogenesis forming the median artery, ulnar artery and the superficial brachial artery.
He also recorded the bifurcation of brachial artery I into radial and ulnar arteries in cubital fossa, and further continuation of brachial artery II as common interosseous artery.

Variations in the divisions of the brachial artery have been reported, the brachial artery divides more proximally than usual into radial, ulnar and common interosseous artery. The anomalous brachial vessels sometimes result from high division of brachial artery with two arteries proceeding to the cubital fossa instead of the usual one [2, 3].
In which, the common trunk further divided into three branches, the ulnar, median and common interosseous artery (fig.1).
