What supplies the superior mesenteric artery

The superior mesenteric artery is in the midsection of the digestive tract (midgut). It originates from the aorta between the celiac artery and renal arteries. The celiac artery supplies blood to the liver, spleen and stomach. The renal arteries send blood to the kidneys.

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.

What does superior mesenteric vein supply?

The superior mesenteric vein (SMV) is a large blood vessel in the abdomen. Its function is to drain blood from the small intestine as well as the first sections of the large intestine and other digestive organs. This large vein receives blood from several other veins (tributaries) in the digestive tract.

What artery supplies 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 supplies the inferior mesenteric artery?

The branches of the inferior mesenteric artery include 1) the left colic, which is located retroperitoneally and supplies the descending colon; 2) the sigmoid branches, which supply the sigmoid colon; and 3) the superior rectal artery, which is the terminal branch of the inferior mesenteric artery at the pelvic brim.

What artery supplies the duodenum?

The proximal segment of the duodenum is supplied by the gastroduodenal artery and its branches which include the superior pancreaticoduodenal artery. The distal segment of the duodenum is supplied by the superior mesenteric artery and the inferior pancreaticoduodenal artery.

What artery supplies the stomach and duodenum?

Structure and Function The celiac artery gives rise to three major branches, including the left gastric, splenic, and common hepatic arteries. Collectively, these major branches of the celiac artery supply the stomach, spleen, liver, gallbladder, abdominal esophagus, pancreas, and duodenum.

Article first time published on

What artery supplies the stomach?

The relationship of the stomach to surrounding structures is depicted in the figure. The arterial supply to the stomach is derived primarily from the celiac axis. The celiac axis arises from the proximal abdominal aorta and typically branches into the common hepatic, splenic, and left gastric arteries.

What artery supplies the foregut?

The celiac trunk is the principal (but not exclusive) artery supplying the foregut. The celiac trunk arises from the abdominal aorta.

What vessel travels posterior to the superior mesenteric artery and anterior to the abdominal aorta?

The left renal vein most commonly follows a course between the superior mesenteric artery (SMA) anteriorly and the aorta posteriorly, although it may also pass posterior to the aorta (retroaortic or circumaortic renal vein).

Which artery supplies the splenic flexure?

The marginal artery, also known as the artery of Drummond, supplies the proximal descending colon at the splenic flexure. The artery of Drummond is an arterial arcade formed by an anastomosis between the distal branches of the superior and inferior mesenteric arteries.

What does the superior and inferior mesenteric artery supply?

The superior mesenteric artery supplies the midgut and the inferior mesenteric artery supplies the hindgut. … It supplies the distal third of the transverse colon, the splenic flexure, the descending colon, the sigmoid colon and the rectum, as well as the superior part of the anal canal down to the dentate line.

What does celiac trunk supply?

Its major branches include the celiac trunk, superior mesenteric artery, and inferior mesenteric artery. The first major branch, which comes off anteriorly at the T12 level, is the celiac trunk. It supplies oxygen-rich blood to the spleen, and structures derived from the embryonic foregut.

What does superior mesenteric plexus supply?

It surrounds the superior mesenteric artery, accompanies it into the mesentery, and divides into a number of secondary plexuses, which are distributed to all the parts supplied by the artery, viz., pancreatic branches to the pancreas; intestinal branches to the small intestine; and ileocolic, right colic, and middle …

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.

What is the difference between ileum and jejunum?

Jejunum refers to the mid section of the small intestine while ileum is the lengthiest and the last part of the small intestine before the large intestine starts. … Jejunum has minor traces of Mucosa Associated Lymph Tissue while Ileum has major amounts of Mucosa Associated Lymph Tissue.

What is the mesentery?

The mesentery is a fold of membrane that attaches the intestine to the abdominal wall and holds it in place. Mesenteric lymphadenitis is an inflammation of the lymph nodes in the mesentery.

What is the function of the inferior mesenteric vein?

The main function of the inferior mesenteric vein is to drain blood from the hindgut, a portion of the gastrointestinal tract that includes the structures from the distal transverse colon to the rectum.

What drains into splenic vein?

The splenic vein (formerly the lienal vein) is a blood vessel that drains blood from the spleen, the stomach fundus and part of the pancreas. It is part of the hepatic portal system.

How long is jejunum?

The jejunum is roughly 2.5 meters in length, contains plicae circulares (muscular flaps), and villi to absorb the products of digestion. The ileum is the final portion of the small intestine, measuring around 3 meters, and ends at the cecum.

Is jejunum the same as duodenum?

Jejunum Overview It extends from the pyloric sphincter of the stomach to the ileocecal valve that connects the small intestine to the large intestine. The other two sections are called the duodenum and the ileum. The jejunum is located between the duodenum and the ileum.

What does the superior phrenic artery do?

The superior phrenic arteries are small branches arising either side from the lower part of the thoracic aorta just before it passes through the aortic hiatus. They anastamose with the pericardiophrenic and musculophrenic arteries to supply the superior surface of the diaphragm.

Which artery supplies the small intestine with blood quizlet?

The superior mesenteric artery supplies the distal portions of the small intestine: the jejunum and ileum.

What are the three mesenteric arteries?

Its branches are the left colic artery, the sigmoid (inferior left colic) arteries, and the superior rectal artery. The SMA and IMA collateralize via the marginal artery of Drummond and the meandering mesenteric artery.

What vertebral level is the superior mesenteric artery?

The origins of all the branches varied between exactly two vertebral levels (Fig. 2). The celiac artery originated at T11/T12–L1/L2, followed by the superior mesenteric artery at T12–L2, the paired renal arteries at T12/L1–L2/L3, the inferior mesenteric artery at L2–L4, and the common iliac arteries at L3–L5.

What does the superior Pancreaticoduodenal artery supply?

The superior pancreaticoduodenal artery is a branch of gastroduodenal artery that supplies the duodenum and pancreas.

What aortic branch supplies the stomach?

The stomach is supplied by a rich system of arteries derived from the celiac trunk, the first major visceral branch of the abdominal aorta. The lesser curvature of the stomach is supplied by the left and right gastric artery, which are branches of the celiac trunk and the common hepatic artery respectively.
