with microvilli (secretion and
absorption) and goblet cells (mucus)
Lamina propria – contains lacteals
Between villi = intestinal glands (crypts of Lieberkuhn)
Submucosa is thrown up into folds = Plicae Circularis
Muscularis - 2 layers of smooth muscle; outer longitudinal layer and
inner circular layer
Digestive System II
Notes Continued from 1 April 2013
most chemical digestion occurs here because;
the duodenal cells of the intestinal glands
make enzymes to break down
it receives bile from the gall bladder.
it receives enzymes from the pancreas for the breakdown of food
Common Bile Duct
(from gall bladder
(surrounded by the hepatopancreatic sphincter)
most absorption occurs here
Ileum: has very little absorption.
Most Chemical Digestion occurs in the
duodenum and digestion is completed in Small Intestine. The small intestine ends at
the Ileocecal valve
Which of the following contains 3 layers of smooth muscle in its muscularis?
