Q

What are the retroperitoneal organs (5)

A
  • Kidney & ureter
  • Adrenal gland
  • Aorta
  • IVC
  • Pancreas
20
Q

These organs are secondarily retroperitoneal (4)

A
  • Duodenum
  • Ascending colon
  • Descending colon
  • Rectum
21
Q

What are the sub-peritoneal organs (4)

A
  • Bladder
  • Ovaries
  • Uterus
  • Uterine Tubes
22
Q

This is a continuation between the visceral and parietal peritoneum
-Double layered

A

Mesenteries

23
Q

What is carried in the mesentery?

A
  • Means for neurovascular communication between organs and the body wall
  • Contains fat, lymph, and vessels
24
Q

What are the ligaments of the liver?

A
  • Falciform ligament
  • Coronary
  • Triangular ligaments (right and left)
25
Q

What are the 3 components of the greater omentum

A
  • Gastrocolic
  • Gastrosplenic
  • Gastrophrenic
26
Q

What are the 2 components of the lesser omentum

A
  • Hepatoduodenal

- Hepatogastric

27
Q

This hangs from the greater curvature of the stomach and proximal duodenum and reflects back to attach to the transverse colon and the mesentery

A

Greater omentum

28
Q

This connects to the lesser curvature of the stomach and proximal duodenum to the liver

A

Lesser omentum

29
Q

What is included in the postal triad?

A
  • Hepatic artery
  • bile duct
  • hepatic portal vein
30
Q

What does the portal triad travel in?

A

Within the hepatoduodenal ligament at the free edge of the omentum

31
Q

This is the main larger part of the peritoneal cavity

A

Greater sac

32
Q

What are the 2 components of the greater sac?

A
  • Supracolic

- Infracolic

33
Q

This is superior to the transverse mesocolon

-Contains the stomach, liver, and spleen

A

Supracolic compartment of the greater sac

34
Q

This is inferior to the transverse mesocolon and it contains the SI, ascending and descending colon

A

Infracolic compartment of the greater sac

35
Q

These spaces are separated by the mesentery of the SI

A

Right and left infracolic spaces

36
Q

These 2 spaces are connected by the right and left paracolic gutters

A

Supracolic and infracolic spaces

37
Q

What are the recesses of the greater sac?

A
  • Subphrenic
  • Subhepatic
  • Hepatorenal (morrisions pouch)
38
Q

This lies between the ascending and descending colon and the posterolateral abdominal wall

A

Paracolic gutters

39
Q

What is another name for the lesser sac?

A

Omental bursa

40
Q

Where does the lesser sac lie?

A

Posterior to the stomach, lesser omentum, and adjacent structures

41
Q

This is the communication/passageway from the greater sac to the lesser sac

A

The omental foramen (epiploic foramen, or foramen of winslow)

42
Q

What are the boundaries of the lesser foramen

A
  • Anterior= portal triad (hepatoduodenal ligament)
  • Posterior= IVC and right crus of the diaphragm
  • Superiorly= liver
  • Inferiorly= first part of the duodenum
43
Q

Describe the superior recess of the lesser sac

A

-Extends superiorly between the liver and the diaphragm

44
Q

Describe the inferior recess

A
  • Open during infancy when the layers have not fused

- Only extends as far as the transverse colon

45
Q

How can the posterior wall of the stomach be accessed

A

Through the lesser sac
