Digestive Tract
Oral Cavity
Possesses tounge for food manipulation.
Salvatory Glands
Dissolve Flavorents, Saliva, Lubricates, Produces Enzymes, Can be Venom distributes.
Teeth
Bone or Keratin. Balen is keratin and in Whales.
Esophagus functions (Normal)
Swallowing, Goes from skeletal muscle to smooth, Mucus glands,
Esophagus (Bird)
Leads to the Crop and Rumin (Foregut fermenters)
Crop
In birds, Food storage and grinding
Rumin
In foregut fermenters, Microbial digestion of cellulose
Stomach (Normal)
Food Storage, Mucosal Folds, 3 muscle layers (Mixing), Rugae for stretch, Gastric pits and glands.
Gastric Pits and glands
In the stomach, aid in digestion and secrete gastric Juice.
Gastric Juice
Hydrochorid acid and Mucus (Protection and digestion)
Protelyric enzymes and Mucus (Protection)
Bird Stomach parts

Chyme
Digestive product. Acidic Liquid that enters the Duodeum of small intestine
Duodeum
Takes Chyme from stomach along with enzymes from the pancreas, bile from the liver and Alkaline mucus from Brunners gland to neutralize.
Small intestine
Lined with Enterocytes, receives from the Duodeum
Enterocytes
Preform obsorbtion in the small intestine, digestion, and (Large area) are favored by nature.
How is Enterocytes surface area increases
Long length, Internal Folds, Microvilli.
increases it 600x
Large intestine
Cecum joins Small intestine to large. Obsorbs feces and H2O
Cecum
Adjoins Small and Large intestine. Houses an Appendix
In hindgut fermenters, Cecum expanded to accommodate microbial digestion of cellulose.
Appendix
Lymphadic organ, housed in the cecum.
Composition of Feces
1/3 home cells
1/3 bacteria
1/3 in-digestable material (Like cellulose)
It is mostly water, these are addition to it
What systems control an animals water budget?
