mucosa alimentary canal structure
first that digesta interacts with
interface with lumen
absorption and secretion
submucosa structural and immune cells
muscularis muscle for motion
keeps digesta moving
serosa interact with body cavity
mouth chewing (mechanical digestion)
pharynx initiation of swallowing reflex
salivary glands moisten food, lubrication, polysaccharide
(digesting enzyme) --mucus, amylase
esophagus move food to stomach by peristaltic waves,
lubrication (mucus)
stomach function solubilization of food, kill microbes (HCl)
protein-digesting enzyme (pepsin)
lubricate and protect epithelial surface (mucus)
store, mix, dissolve food, regulate emptying
pregastric functions prehension, mastication, swallowing
humans=food, animals=feed
mouth, esophagus, pharynx, salivary gland
prehension food to mouth, varies the most
mastication chewing, break down bolus, physical reduction

salivation lubricate bolus, help feed be swallowed
3 major glands
3 major glands of salivation parotid (watery, enzymes, ions, start digestion)
sublingual (mucous, lubricate)
submaxillary (mixed, mucus, ions, enzymes, water,
both jobs)
functions of saliva moisten feed (ions, water)
lubrication (aids swallowing)
starch digestion (amylase)
nitrogen recycling (urea)
rumen pH buffering
specialized functions
deglutition (swallowing) most similar, reflex initiated by presence of food in
pharynx (stops respiration)
propulsion of food to stomach by esophageal
peristalsis (involuntary)
major functions of gastric digestion mixing, mechanical breakdown
hydrolytic digestion by acid enzymes
reservoir for controlled release of digesta to SI
stomach size, shape varies
lined by nonglandular or secretory epithelium
functions: storage, mixing, partial digestion
limited absorptive capacity
esophageal (nonglandular) section of the stomach
no actual function
nonglandular (prevents rise of acid)
sphyncter that shuts esophagus and esophageal
region

human stomach = 10 pH
pariental=pH=HCl
pepsinogen activated by low pH
pepsinogen-pepsin/HCl-pepsin-ingested protein-
short peptides
pyloric region mucus secreting
endocrine G cells (gastrin, HCl by parietal)
cephalic phase vagal reflex
increased gastric motility
enzyme and HCl secretion
gastric phase depends on presence of food
gastrin (peptide hormone)
increased HCl and pepsinogen
intestinal phase duodenal distension, osmolarity, nutrients,
decrease HCl and gastric motility, secretin, CCK
pancreas enzymes and bicarbonate
digest carbs, fats, proteins, nucleic acid
neutralize HCl
