If an organ is not part of the gut tube then it is what type of peritoneum
primary retroperiteneal
if an organ is part of the gut tube and does not have a mesentery then it is?
secondarily retroperiteneal
intraperitoneal organs (have mesentery and completely covered by peritoneum)
SSSLL Good Call
spleen, stomach, small intestine, Liver, large intestine, gallbladder, cecum/appendix
also uterus, ovaries, and uterine tubes
intraperitoneal organs general relations of viscera to peritoneum
covered on most sides by visceral peritoneum and suspended by mesentery from the body wall
primarily retroperitoneal organs
Go KU AIA

secondarily retroperit organs
descending colon, ascending colon, pancreas, duodenum
THE Mesentery
attaches the SI to the posterior body wall
ventral mesentery attached to the stomach
mesogastrium
ventral mesentery and attachment
from respiratory diaphragm to duodenum, attaches liver

medial inguinal fossa
between medial and lateral folds, site for direct hernias (inguinal triangle)
lateral inguinal fossa
lateral to lateral fold, site for indirect inguinal hernias
