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.
