between the peritoneal layers

How is the lesser omentum connected to the liver?

Hepatogastric ligament connects the liver to the stomach
Hepatoduodenal ligament connects the liver to the duodenum and contains the portal triad

What is the portal triad?

It is comprised of the hepatic artery, portal vein, and bile duct

10

What is the purpose of the mesentary proper?

It anchors most of the small intestine to the posterior abdominal wall

by the suspensory ligament of Treitz

12

T/F the suspensory ligament of Treitz is a fibrous ligament?

False, it is a fibromuscular ligament.

13

What is the purpose of the suspensory ligament of Treitz?

It keeps the juodenaljejunal junction from sagging

14

What is the purpose of the mesocolon?

It anchors portions of the colon to the posterior abdominal wall.

Do the ascending and descending colon have mesentary?

Nope

16

How is the ascending and descending colon anchored?

It is attached directly to the posterior wall

17

How is the transverse colon anchored?

Via the transverse mesocolon

18

How is the sigmoid colon anchored?

Via the sigmoid mesocolon

19

T/F the rectum is only partly covered with peritoneum?

Truth

20

What does the falciform ligament do?

1. It divides the liver into right and left lobes
2. It anchors the liver to the diaphragm and anterior body wall

21

The falciform ligament

22

What does the coronary ligament do?

It attaches the liver to the inferior surface of the diaphragm

23

The coronary ligament borders what?

The bare area (upper posterior) of the liver

24

____ covers the fetal urachus

1 median umbilical fold

25

2 medial umbilical folds cover _____

the fetal umbilical arteries

26

2 lateral umbilical folds cover _____

the inferior epigastric vessels

Peritoneal pouches are potential spaces in _____ patients.

Standing

28

What are the two peritoneal pouches?

Hepatorenal pouch
Rectovesical/retrouterine pouch

29

Clinically speaking, what can accumulate in the peritoneal pouches?

pathological fluids

30

What is the hepatorenal pouch bound by? (4 things)

the liver, right kidney, colon, and duodenum

31

Which one is more superior, the hepatorenal pouch or rectovesical/rectouterine pouch?

the hepatorenal pouch

32

Know how the pouches can drain into each other.

Okay

33

Where is the rectovesical/rectouterine pouch located?

between the rectum and uterus

34

What is the liver's job?

detoxifies chemical products and produces bile

35

What is the gall bladder's job?

stores bile for emulsification of fats

36

What does the pancreas do?

It produces enzymes for digestion

37

What does the spleen do?

It produces lymphocytes and filters blood

38

What does the stomach do?

It stores food prior to entering the duodenum

39

What does the small intestine do?

It is for primary chemical digestion

40

What does the large intestine do?

it is secondary for chemical digestion

41

What is the kidney's job?

Filter waste products out of blood

42

What do the adrenal glands do?

Cortex that produce steroid hormones and medulla acts as a sympathethic ganglia

43

The gallbladder is attached to what, where?
