A

left and right hepatic artery

25
Q

at what point does the common hepatic artery become the hepatic proper artery

A

when the gastroduodenal artery branches off it

26
Q

which part of the duodenum separates the foregut and midgut

A

2nd part (descending)

27
Q

which major branch of aorta supplies the midgut

A

superior mesenteric

28
Q

what artery supplies the lower part of pancreas and duodenum

A

inferior anterior/posterior pancreaticoduodenal artery

29
Q

not the superior and inferior pancreaticoduodenal arteries anastomose

30
Q

what artery supplies the small bowel

A

jejuenal and illeal artery

31
Q

what structure does the large intestine meet the small intestine at

A

ileocaecal junction

32
Q

where does the midgut meet the hindgut

A

2/3 along the transverse colon

33
Q

what artery supplies the middle of the large intestine

A

middle colic

34
Q

what artery supplies the right side of large intestine

A

right colic

35
Q

which artery supplies the ileocaecal junction

36
Q

which artery supplies the appendix

A

appendicular

37
Q

which artery supplies the edge of large intestine

A

marginal artery of drummond

38
Q

which branch off the aorta supplies the hind gut

A

inferior mesanteric

39
Q

which vertebral level does the inferior mesenteric artery branch off the aorta

40
Q

which artery supplies the superior part of the rectum

A

superior rectal

41
Q

which artery supplies the left side of the large intestine

A

left colic

42
Q

which artery supplies the sigmoid

A

sigmoid artery

43
Q

define what a watershed area is

A

regions of body that receive dual blood supply

44
Q

what is a negative and positive of watershed regions in terms of ischaemia

A

pro :
- if theres a blockage in one of the arteries that supply a watershed area, they are spared from ischaemia due to dual supply

con :
- if there is systemic hypo perfusion (slow/reduced blood flow) it is extremely vulnerable to ischaemia as it is most distal to branches

45
Q

what are the 3 watershed regions in the large intestine

A
  1. around the SMA ileal branches ( near the junction where the large intestine and small intestine meet)
  2. splenic flexure ( upper left corner of LI) (Griffith point)
  3. rectosigmoid junction (sudeck point)
46
Q

what of the gut does the inferior mesenteric vein drain

47
Q

what vein drains the spleen

A

splenic vein

48
Q

what 2 other structures does the splenic vein drain

A

pancreas and stomach

49
Q

what part of the gut does the superior mesenteric vein drain

50
Q

the superior mesenteric and splenic vein fuse to form which major vein

A

hepatic portal vein

51
Q

why does the venous blood from the gut go to the liver and not inferior vena cava

A
  • substances absorbed by the bowel need to get stored, altered and detoxified first
52
Q

note the lymphatic drainage has the same name as the arteries

53
Q

what lymph node drains to which lymph nodes from the foregut

A

celiac lymph nodes

54
Q

what lymph nodes drain midgut

A

superior mesenteric lymph nodes

55
Q

what lymph nodes drain hindgut

A

inferior mesenteric lymph nodes

56
Q

what is the name fo the structure into which the lymph nodes form the celiac lymph nodes will flow

A

thoracic duct
