A

2
covers medial umbilical ligaments
occuded portions of umbilical aa

23
Q

lateral umbilical folds

A

2

covers inferior epigastric vessels

24
Q

What are peritoneal pouches?

A

Potential peritoneal spaces in standing patients

Become actual spaces in recumbent patients

25
Q

Hepatorenal pouch (Pouch of Morrison)

A

Bound by liver, kidney, colon, and duodenum
Lowest part of peritoneal cavity when recumbent
Fluids move to retrovesical/retouterine pouch when reclined or sitting

26
Q

Rectovesical/rectouterine pouch (males)

A

Between rectum and bladder
Low point of peritoneal cavity when recumbent
Fluids move to hepatorenal pouch when in trendelenburg position

27
Q

Rectovesical/rectouterine pouch (females)

A

Between rectum and uterus
Low point of peritoneal cavity when recumbent
Fluids move to hepatorenal pouch when in trendelenburg position

28
Q

gallblader attachment and contacts

A

Attachment: inferior surface of liver
Contact: duodenum, colon, anterior abdominal wall

29
Q

Gallbladder function

A

Receives biles from liver via bile ducts

Drains into duodenum via bile ducts

30
Q

List the bile ducts

A

R and L bile ducts
Common hepatic duct
Cystic duct
Common bile duct

31
Q

R and L bile ducts

A

receives bile from R and L loves of liver

32
Q

Common hepatic duct

A

Recieves R and L hepatic ducts

33
Q

Cystic duct

A

connected to gall bladder

34
Q

common bile duct

A

connect cystic and common hepatic duct

35
Q

Bile duct drainage

A

Common bile duct meets pancreatic duct > major duodenal papilla > descending part of duodenum

36
Q

Parts of pancreas

A

head, neck, body, tail, uncinate process

37
Q

Location of pancreas

A

Retroperitoneal
Transverse across posterior abdominal wall
Surrounded by duodenum on R and spleen on L

38
Q

Main pancreatic duct

A

Enters duodenum w/ bile duct at major duodenal papilla

39
Q

Accessory pancreatic duct

A

Enters duodenum 2 cm to major papilla

40
Q

Spleen location

A

Contacts diaphragm along ribs 9-11

41
Q

What does the celiac trunk supply?

A

Liver, gallbladder, esophagus, stomach, pancreas, spleen

42
Q

Branches of celiac trunk

A

common hepatic, L gastric, splenic aa

43
Q

Common hepatic a. location and path

A

right branch of celiac trunk

towards liver and gallbladder

44
Q

Branches of common hepatic a.

A

proper hepatic a

gastroduodenal a

45
Q

Proper hepatic A. location and path

A

Superior branch of common hepatic a.

Medial to common bile duct
Superficial to portal v.

46
Q

What does proper hepatic a split to?

A

R and L hepatic aa

Supplies R and L lobes of liver

47
Q

Gastroduodenal a. location and path

A

Inferior branch of common hepatic a

Runs towards junction of stomach and duodenum

48
Q

Gastroduodenal branches

A

superior pancreaticoduodenal aa > pancreas/duodenum
R gastroepiploic a > greater curvature of stomach
supraduodedenal a > superior duodenum

49
Q

L gastric A path

A

Superior branch of celiac trunk
Runs L towards lesser curvature
Supplies stomach and esophagus

50
Q

Splenic A

A

L branch of celiac trunk
Runs towards spleen
supplies pancreas and spleen

51
Q

Splenic A. branches

A

short gastric aa, L gastroepiploic a

Supply greater curvature of stomach

52
Q

R. Gastric a

A

from proper hepatic
May arise from common hepatic or gastroduodenal aa.
Anastomoses with L. gastric a
Supplies lesser curvature of stomach
