Celiac Trunk Branches
Celiac Trunk Branches
The Celiac Trunk, a major branch of the abdominal aorta, supplies blood to the stomach, liver, spleen, and pancreas. It has branches like the splenic artery, left gastric artery, and common hepatic artery.
Superior Mesenteric Artery
Superior Mesenteric Artery
A branch of the abdominal aorta supplying blood to the small intestine (jejunum and ileum) and parts of the large intestine (ascending and transverse colon).
Inferior Mesenteric Artery
Inferior Mesenteric Artery
A branch of the abdominal aorta supplying blood to the distal parts of the large intestines (descending colon, sigmoid colon, and rectum).

Study Notes
Abdominal Aorta Branches
- The abdominal aorta branches into various arteries supplying blood to the abdominal organs and lower body.
- Major branches include the celiac trunk, superior mesenteric artery, and inferior mesenteric artery.
- The celiac trunk supplies the stomach, liver, pancreas, and spleen.
- The superior mesenteric artery supplies the small intestine and part of the large intestine.
- The inferior mesenteric artery supplies the remaining part of the large intestine.
- Other branches include renal arteries (kidneys), gonadal arteries (gonads), and lumbar arteries (back).
Celiac Trunk
- The celiac trunk is a short, major branch of the abdominal aorta.
- It originates one centimeter below the aortic hiatus.
- It provides blood supply to the stomach, liver, spleen, and a portion of the pancreas.
- Three main branches of the celiac trunk include:
- Left gastric artery
- Splenic artery
- Common hepatic artery.
Superior Mesenteric Artery
- The superior mesenteric artery supplies blood to the small intestine and part of the large intestine.
- It's located slightly inferior to the celiac trunk.
- Its branches include:
- Right colic artery
- Middle colic artery
- Inferior pancreaticoduodenal artery and branches to the small and large intestine
Inferior Mesenteric Artery
- The inferior mesenteric artery supplies the distal portion of the large intestine.
- It is located inferior to the superior mesenteric artery.
- Its branches include:
- Left colic artery
- Sigmoid arteries
Clinical Considerations
- Understanding the distribution of these arteries is crucial for diagnosing and treating conditions affecting the abdominal organs.
- Blockages or damage to these arteries can impede blood flow, causing ischemia (lack of blood supply) and potentially organ damage.
- Accurate knowledge of where these arteries branch from and their distribution helps surgeons during procedures.
Additional Arteries
- Renal arteries: Supply the kidneys.
- Gonadal arteries: Supply the gonads (testes or ovaries).
- Lumbar arteries: Supply the lumbar region of the back.
- Middle sacral artery: supplies the lower sacrum and coccyx.
- Common iliac arteries: further branching to internal and external iliacs. Providing blood to the pelvic and lower limbs.
