Muscoa: no plicae circularis or villi bc little

Simple columnar w same cells as small but
Goblet cells increase for lub
Strat squamous in anal canal, deeper
intestinal glands (crypts), accumulations of
lymphatic tissue in lamina propria and

Submucosa: normal
Muscularis externa:
Taeniae: outer long layer made of 3
smooth bands
Hasutra: series of pouches in wall of colon,
created by muscle tone in taeniae, permit
elongation and expansion
Circular muscle thickens to form sphincter
in anal canal
Liver
Starts at 5th rib9th largest visceral organ
(1.5kg), wrapped in fibrous capsule
Diaphragmatic (superior & anterior) and
visceral (posterior) surfaces
R largest lobe, R+ L lobe on superior
surface, caudate located left to fossa of
vena cava on posterior surface, quadrate
located next to gall bladder fossa on
inferior surface below caudate
Peritoneum: completely covered except
base area b/n 2 coronary lig, visceral-
stomach, duodenum, gall bladder, R kidney
+ R colic flexure
Falciform lig: peritoneum, attaches liver to
anterior ab wall, sep R and L lobes and
make coronary lig, reminant of umbilical
vein
Round lig: fibrous band in free margin of
falciform lig
Coronary lig: contains bare area, suspend
liver from inferior diaphragm surface
