Definition: Omentum

Peritoneum connecting two organs

Definition: Mesentery

Double layer of peritoneum connecting organ to abdominal wall

- Intraperitoneal (organs suspended by a mesentery

- Retroperitoneal (organs posterior to the parietal peritoneum)

Greater Omentum

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

Lesser Omentum

Runs from the Liver to the Lesser Curve of the Stomach - located superiorly to the stomach

Mesentery Proper

Attached to the small intestine (only mesentery named NOT for what it is attached too) from the posterior wall to the jejunum and ileum of the small intestine

Falciform Ligament

Runs from the ventral body wall to the ventral surface of the liver

Ventral Mesenteries give rise to...

the Falciform Ligament and Lesser Omentum

Dorsal Mesenteries give rise to...

the Greater Omentum, Transverse Mesocolon, and Mesentery Proper

List of Retroperitoneal Organs: - 9

1. Duodenum

2. Pancreas

3. Kidneys

4. Ureters

5. Cecum

6. Ascending Colon

7. Descending Colon

8. Aorta

9. Inferior Vena Cava

Paired Arteries of the Abdomen, and what they supply

1. renal aa.

2. gonadal aa.

3. lumbar aa.

Supply the kidneys, gonads, and posterior abdominal wall

Unpaired Arteries of the Abdomen, and what they supply

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

Blood Trace - From Abdominal Aorta to the Greater Curvature of Stomach (Right Side)

Abdominal Aorta > Celiac Trunk > Common Hepatic a. > Gastroduodenal a. > Right Gastroepiploic a. > Capillary beds of Stomach Wall

Blood Trace - From Greater Curvature of Stomach to Right Atrium (right side)

Capillary beds of Stomach > Right Gastroepiploic v. > Superior Mesenteric v. > Hepatic Portal v. > Capillary beds of Liver > Hepatic vv. > Inferior Vena Cava

Branches of the Common Hepatic a.

1. Right Gastric a.

2. Hepatic Proper a.

3. Right Gastroduodenal a.

Superior Mesenteric a. supplies what?

Gut tube from the duodenum to the left colic flexture (and organs inbetween)

Inferior Mesenteric a. supplis what?

Gut tube from left colic flexture to the rectum (and such organs inbetween)

Marginal a.

Branches of the SMA and IMA anastomose to form this; which gives rise to small branches of straight aa. that supply blood and absorb nutrients in the small and large intestines

Straight aa.

Enter the walls of the small and large intestines to supply blood and absord nutrients, etc

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:

Have the same names as the arteries, and drain into the hepatic portal system

Hepatic Portal System

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

The Hepatic Portal Vein carries blood to the liver for three things:

1. To supply the liver oxygen

2. Deliver glucose for storage

3. For blood detoxification

What two veins unite to form the Hepatic Portal v.?

- Superior Mesenteric v.

- Splenic v.

Abdominal Viscera Innervations

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
