The celiac trunk gives off branches to the diaphragm, then divides into three main branches, the small left gastric artery which goes straight up, and the large common hepatic, and splenic arteries, which go to the right and left.

What are mesenteric arteries?

The mesenteric arteries take blood from the aorta and distribute it to a large portion of the gastrointestinal tract. Both the superior and inferior mesenteric arteries arise from the abdominal aorta. Each of these arteries travel through the mesentery, within which they branch several times before reaching the gut.

What is SMA and SMV?

The smaller superior mesenteric vein (SMV) sign is a well‐known computed tomography (CT) parameter for acute superior mesenteric artery (SMA) occlusion. This CT sign is potentially beneficial for the early diagnosis of acute SMA occlusion; however, few reports have documented this sign.

What artery branches off the subclavian arteries?

Branches. The subclavian arteries give off five major arteries each: the vertebral artery, the internal thoracic artery, the thyrocervical trunk, the costocervical trunk, and the dorsal scapular artery.

What artery supplies the small intestine cecum ascending colon and transverse colon quizlet?

The superior mesenteric a. supplies all of the small intestine (except for the proximal portion of the duodenum), the vermiform appendix, the cecum, the ascending colon, and the transverse colon.

Which organ is supplied with blood by the renal artery?

The renal arteries deliver to the kidneys of a normal person at rest 1.2 litres of blood per minute, a volume equivalent to approximately one-quarter of the heart’s output. Thus, a volume of blood equal to all that found in the body of an adult human being is processed by the kidneys once every four to five minutes.

What is the inferior mesenteric vein?

The inferior mesenteric vein drains the mesenteric arcade of the hindgut (comprising of distal transverse, descending, and sigmoid colon). Specifically, it drains the tributaries of sigmoid veins, middle and left colic veins, as well as the superior rectal vein.

What is the inferior mesenteric ganglion?

The inferior mesenteric ganglion is a ganglion located near where the inferior mesenteric artery branches from the abdominal aorta.

Why hindgut is supplied by the branches of inferior mesenteric artery?

The inferior mesenteric artery (IMA) is a major branch of the abdominal aorta. It supplies arterial blood to the organs of the hindgut – the distal 1/3 of the transverse colon, splenic flexure, descending colon, sigmoid colon and rectum.

Which branch of the aorta supplies the jejunum?

Jejunal and ileal arteries: Supply blood to the jejunum (midsection of the small intestine) and part of the ileum (last part of the small intestine).

What artery supplies the jejunum?

The jejunal and ileal branches supply the jejunum and ileum, respectively. The ileocolic artery supplies the distal ileum, cecum, and proximal ascending colon.

What artery supplies second part of duodenum?

Proximal to the 2nd part of the duodenum (approximately at the major duodenal papilla – where the bile duct enters) the arterial supply is from the gastroduodenal artery and its branch the superior pancreaticoduodenal artery.

Which branch of the celiac trunk supplies blood to the spleen part of the stomach and pancreas?

Splenic artery: This artery offers multiple branches to the upper and middle parts of the greater curvature and fundus of the stomach as well as to the pancreas. This artery ends its course by providing oxygenated blood to the spleen.

What side is the superior mesenteric artery?

The superior mesenteric arterys initial course is forwards and downwards, and it travels posterior to the neck of the pancreas and the splenic vein. The superior mesenteric artery is usually found running to the left side of the superior mesenteric vein (which drains the same region as the artery supplies).

What are the three anterior branches that supply the gastrointestinal viscera?

The GIT is supplied by the three anterior branches of the abdominal aorta. From superior to inferior, these include the celiac trunk, SMA, and IMA. These three branches are unpaired and their terminal branches anastomose to provide the collateral supply.
