Animals digestive tract
Foregut
Mouth
:check:Tongue(obtaining food)
:check:Teeth(chewing)
:check:Saliva(lubricating) 
Esophagus
:check:As passage to move food from mouth to stomach
Midgut
Stomach
:check:food digestion
:check:food absorption(ruminants)
Intestine
:check:digestion and absorption
Hindgut
Large intestine
:check:H2O and ion reabsorption
:check:microbial digestion (horse, rabbit)
Rectum
:check:faeces formation take place
:check:temporary faeces storage
Foraging foods methods
Simple minded
:check:not required high skills to obtain food :check:food is easy to find usually :check: ex: cow, sheep, goat
Takes time
:check:required skills
:check:food usually hard to obtain
:check:ex: crocodile, tiger, eagle
Food digestion processes
Intracellular
:check:simple but incomplete and less effiicient
:check:unicellular and multicellular organisms
:check:food enter cell by phagocytosis or pinocytosis
:check:food break down by lysosomes
:check:ex:bacteria, protozoa
Extracellular
:check:complex but complete and more efficient
:check:unidirectional
:check:"bile" neutralize stomach acidity
:check:digestion outside the cell
:check:ex: annelides, arthropods, vertebrates
Digestion system of fish
:check: Absorption of nutrient occur at intestine :check: Pyloric caeca :pencil2: Secrete digestive enzyme to neutralize acidity of chyme :check: Spiral Valve :pencil2: Increase surface area
-
-
Digestion system of aves
:check: Need to consume more food because of high metabolic rates :check: Crop :pencil2: Store food tempororaly and milk production :check: Proventriculus :pencil2: Secrete HCl, pepsinogen and mucus :check: Bird gizzard :pencil2: Very thick muscular wall
-
Control metabolism level
Metabolites detection
:check:controlled by hypothalamus in brain
:check:for involuntary action
:check:controlled hunger and satiety
Long term control
:check:Fat deposition
:check:as energy supply
:check:white adipose tissue
:check:secretes hormone leptine
:check:hormone leptine stimulates production of neuropeptides
:check:neuropeptides reduce food intake
