what does the omasum do ?
strains or sorts materials between the rumen and resorts gastrointestinal tract
what does the abomasum do ?
gastric stomach with chemical digestion
proximal small intestine
digestion and absorption
distal small intestine
absorption of nutrients
cecum
microbial digestion
large intestine
H2O metabolism
how do we establish microbial population
coprophagy
what is an avian ?
modified monogastric

prehension no mastication no chemical digestion
what does the esophagus of an avian do ?
one way transports from the mouth to the crop
what is a crop
pouch outside body cantis, storage + mild chemical digestion- soften
what is the proventriculus
chemical digestion and gastric stomach
what is the gizzard
mastiation, mechanical digestion
what is grit
small rocks. hard surfaces to go in mechanical digestion provides minerals
