| 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 |
