Question Answer
Structure of the stomach? Wall is muscle w/ inner mucus membrane, mixes food (gastric juices) + kills bacteria (hydrochloric acid)
Saccus caecus region Top third of stomach non-glandular / squamous region, no mucous membrane so susceptible to ulcers
Fundic + pyloric regions Gastric juices continuously secreted, food in stomach approx. 20 mins > leave via pyloric sphincter
Duodenum, Jejunum and Ileum Duodenum - pancreatic + bile ducts Jejunum - majority of absorption Ileum - cont. absorption
What disorders are there? Choke, gastric ulcers, colitis, laminitis, colic, metabolic syndrome
Path of avian digestion Bill > mouth > tongue > pharynx > esophagus > crop > stomach (proventriculus + gizzard) > small int. > caeca > rectum > cloaca
What is the crop for When eating seeds some will go straight to the gut but some are stored in the crop, so after the first round of seeds are digested the rest will auto. refill stomach
Proventriculus 1st chamber, secretes acid to break down food (best developed in birds swallowing entire fish / animals with bones)
Gizzard 2nd chamber, grinds + digests tough food w/ powerful muscles, grit accumulates here where they’re grinded against and smash seeds
What does the caeca do? Aid in absorption of water + proteins and microbial decomposition of fiber
What does the cloaca do? Waste accumulates here before being dumped
