The right and left gastroepiploic arteries (also known as gastroomental) provide the sole blood supply to the greater omentum. Both are branches of the celiac trunk . The right gastroepiploic artery is a branch of the gastroduodenal artery , which is a branch of the common hepatic artery , which is a branch of the celiac trunk.
In human anatomy, the inferior mesenteric artery (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. The regions supplied by the IMA are the descending colon, the sigmoid colon, and part of the rectum. [1]
Along with branches of the internal iliac arteries, it is usually sufficiently large to supply the oxygenated blood to the large intestine. [1] This means that the inferior mesenteric artery does not have to be re-implanted (re-attached) into the repaired abdominal aorta in abdominal aortic aneurysm repair. [1]
The term "intestinal arteries" can be confusing, because these arteries only serve a small portion of the intestines. They do not supply any of the large intestine. The large intestine is primarily supplied by the right colic artery, middle colic artery, and left colic artery. They do not supply the duodenum of the small intestine.
The left colic flexure or splenic flexure (as it is close to the spleen) is the sharp bend between the transverse colon and the descending colon.The splenic flexure receives dual blood supply from the terminal branches of the superior mesenteric artery and the inferior mesenteric artery.
The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in tetrapods. Water is absorbed here and the remaining waste material is stored in the rectum as feces before being removed by defecation . [ 1 ]
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
The celiac (/ ˈ s iː l i. æ k /) artery (also spelled coeliac in British English), also known as the celiac trunk or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 1.25 cm in length.
