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.

, 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.

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.

DISCUSSION: Thrombosis of the celiac artery trunk is a rare cause of acute abdominal pain.
2,3) If the recipient hepatic artery or celiac artery is stenosed, an aorto-hepatic jump graft (usually the donor iliac artery) may be required.
Observation 3: The right and left inferior phrenic artery arises from the trunk of celiac artery instead of arising as lateral branches of the abdominal aorta -1 case (Figure 3).
The hepatic arterial anastomosis is typically an end-to-end fish-mouth anastomosis where the donor common hepatic artery and splenic artery branch point or the origin of the celiac artery with an aortic Carrel patch (small portion of the adjacent aorta surrounding the celiac artery origin) is connected to the recipient right and left hepatic artery bifurcation or the proper hepaticgastroduodenal artery bifurcation.
Close to the transition from the stomach to the intestine, the celiacomesenteric artery bifurcates into the celiac artery and the cranial mesenteric artery, first supplying the hepatic artery and the dorsal cecal artery.
There was conjugate nodal mass at level of gastro duodenal ligament involving CBD, common hepatic artery, celiac artery, duodenum and posterior wall of stomach.
The pathophysiologic changes that underlay the development of true gastroduodenal artery aneurysms comprise mainly atherosclerosis of the celiac artery with subsequent stenosis but also rarely congenital absence of the celiac axis.
A rare case: celiac artery compression syndrome in an asymptomatic child.
Symptomatic celiac artery stenosis due to constr2iction by the neurofibrous tissue of the celiac ganglion.
It arises from the abdominal aorta immediately below the celiac artery, anterior to the lower part of vertebra L1.
The knowledge of this type of variation shows that surgeons must be cautious to avoid unintentional sectioning of small caliper arteries, as it may occur during the celiac artery decompression in the compression syndrome of the celiac trunkby the median arcuate ligament.
