Terms in this set (68)
function of digestive system processes food, extracts nutrients and eliminates residue
the physical breakdown of food into mechanical digestion
smaller parts
A series of hydrolysis reactions that break chemical digestion
dietary macromolecules into their
monomers
6 accessory organs teeth, tongue, salivary glands, liver, gallbladder, pancreas
what makes up the gi tract stomach and intestines
mechanical digestion occurs where grinding of teeth and churning of stomach and small
intestine
, chemical digestion occurs where digestive enzymes produced by salivary glands, stomach,
pancreas, and small intestine
most absorption occurs where small intestine
small mucosal projections that increase villi
surface area for absorption
permanent transverse folds in the intestinal circular folds
lining
four layers of the digestive tract mucosa, submucosa, muscularis externa, serosa
(from inner to outer)
the submucosal plexus is located ____ in the submucosa layer
the myenteric plexus is located between muscularis externa
two layers of the
function of submucosal plexus control glandular secretions of mucosa and movement of
muscularis mucosae
function of myenteric plexus controls peristalsis and other contractions of muscularis
externa
