Double layer of peritoneum connecting organ to abdominal wall
- Intraperitoneal (organs suspended by a mesentery
- Retroperitoneal (organs posterior to the parietal peritoneum)
Attached from the Greater Curve of the Stomach to the anterior surface of intestines - located Anteriorly to Transverse Colon.
"hangs like an apron" and then loops superiorly attaching to posterior body wall
6. Ascending Colon
7. Descending Colon
9. Inferior Vena Cava
1. renal aa.
2. gonadal aa.
3. lumbar aa.
Supply the kidneys, gonads, and posterior abdominal wall
1. Celiac Trunk at T12
2. Superior Mesenteric a.
3. Inferior Mesenteric a.
Supply the digestive organs and spleen
Branches of Celiac Trunk and what they supply
- Left Gastric a.
- Splenic a.
- Common Hepatic a.
Supplies the GI tract down to the Duodenum
1. Right Gastric a.
2. Hepatic Proper a.
3. Right Gastroduodenal a.
Veins with paired arteries have the same:
Names - they drain into the IVC.
EXCEPT the left gonadal v. which drains into the left renal v. which then goes to the IVC
Veins with unpaired arteries:
1. Blood flows through 1st capillary bed
2. then out through vv. to merge with hepatic portal v. (HPV)
3. HPV carries blood to liver
4. Exits liver through hepatic v. and back to IVC
1. To supply the liver oxygen
2. Deliver glucose for storage
3. For blood detoxification
- Superior Mesenteric v.
- Splenic v.
Vagus n. carries parasympathetic fibers to organs down to the left colic flexture
Sacral spinal nn. carries parasympathetic input to the distal gut tube
- Sympathetic (trunk) gives input to ALL abdominal viscera is from the lateral horn of the Spinal Cord
