|
intraperitoneal organs
|
protrude completely in peritoneal sac & almost completely invested by visceral peritoneum
may be mobilized stomach, 1st part of duodenum, liver, pancreas (tail), spleen, jejunum, ileum, transverse colon, sigmoid colon |
|
|
retroperitoneal organs
|
posterior to peritoneum
not easily mobilized kidneys & suprarenal glands, ureters, bladder, aorta, IVC, esophagus (part), rectum (part) |
|
|
secondarily retroperitoneal organs
|
come into contact w/ body wall during development
intraperi organ rotates 7 fuses w/ posterior wall, peri layers fuse & organ covered w/ parietal peri 2nd/3rd/4th parts of duodenum, pancreas (head, neck, body), ascending colon, descending colon |
|
|
greater omentum
|
reflection of peritoneum suspended from greater curvature of stomach & covering ab viscera
provides pathway for NV structures wraps around inflamed organs to prevent peritonitis |
|
|
lesser omentum
|
reflection of peritoneum extending from lesser curve of stomach to liver
pathway for NV structures composed of hepatogastric & heptoduodenal ligaments -hepatoduodenal lig contains portal triad (common bile duct, portal vein, proper hepatic art) |
|
|
greater sac
|
from diaphragm to lower aspect of ab cavity
-supra/infracolic compartments -subphrenic (suprahepatic) recess -subhepatic (hepatorenal) recess (aka morison's pouch on R side) -paracolic recesses/gutters |
|
|
lesser sac
(omental bursa) |
space behind liver, lesser omentum & stomach
|
|
|
omental foramen
|
natural opening b/t lesser & greater sac
boundaries: -caudate lobe of liver -1st part of duodenum -hepatoduodenal lig -IVC |
|
|
mesentary
|
double layer of peritoneum suspends organs from body wall or connects to other organs
blood vessels b/t 2 layers mesentery of small intestine, transverse mesocolon, sigmoid mesocolon, mesoappendix roots: location on posterior wall where parietal peri reflects & forms double layer of mesentery |
|
|
gastrolienal (gastroplenic, lienogastric) ligament
(location & contents) |
from greater curve of stomach to hilum of spleen
contains short gastric & L gastroepiploic vessels |
|
|
lienorenal (splenorenal) ligament
(location & contents) |
from hilum of spleen to L kidney
contains splenic vessles & pancreas tail |
|
|
falciform ligament
(location & contents) |
sickle shaped fold from liver to diaphragm/ab wall
contains ligamentum teres hepatis (round lig of liver ascending from umbilicus to inf liver) and paraumbilical vein |
|
|
coronary ligament
|
2 triangular ligs enclosing "bare area" of liver
peri reflection from liver onto diaphragm |
|
|
ligamentum venosum
|
remnant of ductus venosus lying in fissure on inf surface of liver
|
