It arises about 0.5 cm below the celiac trunk (artery of the foregut) at the level of the intervertebral disc between the L1 and L2 vertebra. The celiac trunk is the first branch of the abdominal aorta and has three branches: the left gastric artery supplies the stomach; the splenic artery supplies the spleen, and the common hepatic artery supplies the liver. The internal iliac artery supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh.The vesicular branches of the internal iliac arteries supply the bladder. Their importance lies with the fact that the right inferior phrenic artery is the most common extrahepatic arterial supply of a hepatocellular carcinoma .

It is a short, thick vessel, smaller than the external iliac artery, and about 3 to 4 cm in length.. It originates on the anterior surface of the aorta at the level of the L1 vertebrae, approximately 1 cm inferior to the celiac trunk and superior to the renal arteries. The marginal artery of Drummond is one of these connections. It can can also arise as the 2nd or 3rd branch from the inferior gluteal artery. The inferior mesenteric artery, also a branch of the abdominal aorta, supplies the distal third of the transverse colon, the descending colon and sigmoid colon, and the superior portion of the rectum as the superior hemorrhoidal artery. The inferior mesenteric artery may be absent entirely, its branches being given by the superior mesenteric artery or it may be just absent from its usual location. The membranous labyrinth is supplied by the labyrinthine artery, a branch of the inferior cerebellar artery (or, occasionally, the basilar artery). It arises a few centimeters from the aortic It begins as a branch of the aorta. (1963) The blood supply of the distal segment of the rectum in anterior resection.

Some sources consider the urethral artery a direct branch of the internal pudendal artery, while others consider it a branch of the perineal artery. It supplies blood to the hindgut, i.e., the distal half of the transverse colon, the descending colon, the sigmoid colon, and the rectum. This is commonly caused by a blood clot, which travels to one of the mesenteric arteries and suddenly blocks blood flow. 77 it is the second most commonly injured abdominal vascular structure following blunt trauma, but penetrating trauma accounts for the significant majority of sma injuries. The marginal artery is almost always present, and its absence should be considered a variant. This one is the left colic artery, which supplies the ascending colon and Variability of splenic flexure blood supply has been described in different ways among literatures: usually, venous drainage from the left colon and splenic flexure formed by several branches that join the inferior mesenteric vein (IMV).

However, the definition in human anatomy refers only to the section of the lower limb extending from the knee to the ankle, also known as the crus or, especially in non-technical use, the shank. It divides into three branches: Cochlear branch supplies the cochlear duct. What do the mesenteric arteries supply? (b) The mesenteric artery gives off the inferior pancreaticoduodenal artery. Structure. It passes downwards, giving off these branches to the colon. Bowel ischemia can affect a small or large intestine and can occur by any cause, which leads to intestinal blood flow reduction. In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal.
