Study Notes
Transversus Abdominis
- Internal intercostals
- Which comes first during inspiration, the expansion of the chest followed by bulk flow of air or bulk flow of air followed by expansion of the chest?
- Expansion of the chest followed by the bulk flow of air
Abdominal Region, Metabolism, & Systems
Arterial supply to abdominal organs/intestines
- Celiac trunk (T12)
- Left gastric artery: To the stomach
- Splenic artery: Supplies the spleen, pancreas, parts of stomach
- Common Hepatic Artery: Supplies liver, gallbladder, pancreas, parts of stomach
- Superior Mesenteric Artery (L1)
- Supplies the right side: Small intestine (except the proximal duodenum), cecum, appendix, ascending colon, and the first part of the transverse colon
- Inferior Mesenteric Artery (L3)
- Supplies the descending colon, sigmoid colon, and rectum
Venous return from abdominal organs/intestines
- Blood from abdominal organs travels to the liver for filtering before returning to the heart.
- Superior Mesenteric Vein
- Small intestine, cecum, ascending colon, right two thirds of the transverse colon, parts of the pancreas and duodenum
- Inferior Mesenteric Vein
- Left one third of the transverse colon, descending colon, sigmoid colon, and the rectum. Typically drains into the splenic vein
- Splenic vein
- Drains the spleen, pancreas, and parts of the stomach; combines with the superior mesenteric vein to form the hepatic portal vein
- Left gastric vein: stomach, connects to splenic vein
- Right Gastric Vein: Right side of the stomach, into the portal vein directly
