Left subcostal and transtubercular plane

50

Pancreas in

Left/right hypochondriac, right lateral, epigastric, umbilical

51

How of jejunum and ileum suspended from posterior ab wall?

Mesentary - means more mobile that duodenum

52

Duodenojejunal junction

Occurs as duodenum emerges from being retorperitoneal

53

Mesenteric windows

Jejunum
Fat kept away from intestinal wall unlike ileum

54
