What does the Ileocolic artery supply?
The ileocolic artery and its branches supply blood to the distal ileum, ileocecal valve, cecum, vermiform appendix, and the proximal ascending colon. The ileocolic artery is found anterior to the right gonadal vessels and ureter. The posterior cecal artery is found posterior to the terminal ileum/cecum.
What artery supplies the jejunum?
Jejunum and Ileum The arterial supply to the jejunoileum is from the superior mesenteric artery. The superior mesenteric artery arises from the aorta at the level of the L1 vertebrae, immediately inferior to the coeliac trunk. It moves in between layers of mesentery, splitting into approximately 20 branches.
What artery supplies the superior mesenteric?
| Superior mesenteric artery | |
|---|---|
| Source | abdominal aorta |
| Branches | inferior pancreaticoduodenal middle colic right colic intestinal branches (jejunal, ileal) ileocolic |
| Vein | superior mesenteric vein |
| Supplies | intestine |
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 part of the colon does the right colic artery supply?
ascending colon
The right colic artery is a branch of the superior mesenteric artery that supplies the ascending colon. It courses to the right towards ascending colon, where it splits into a superior and inferior division.
What artery gives rise to the appendicular artery?
Anatomical terminology The appendicular artery, also known as appendiceal artery, commonly arises from the terminal branch of the ileocolic artery, or less commonly from the posterior cecal artery or an ileal artery. It descends behind the termination of the ileum and enters the mesoappendix of the vermiform appendix.
Is the jejunum part of the colon?
The jejunum helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine connects the stomach and the colon. It includes the duodenum, jejunum, and ileum.
What are the four major arteries that supply the colon?
Arterial Supply
- Right colic artery (from the superior mesenteric artery)
- Middle colic artery (from the superior mesenteric artery)
- Left colic artery (from the inferior mesenteric artery)
Which organs receive blood from the mesenteric arteries?
The superior mesenteric artery arises from the abdominal aorta just below the celiac artery. Its branches supply the small intestine and part of the large intestine.
What artery supplies the gut?
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.
What is the largest vein in the body?
The largest vein in the human body is the inferior vena cava, which carries deoxygenated blood from the lower half of the body back up to the heart.
