Rumination Cycle:
- Regurgitation: throwing the food back up into the mouth from the reticulum
- Reinsalvation: Wetting the food again with saliva to breakdown the food more
- Remastication: rechewing of the food
- Redeglutition: Reswallowing of the food
Teeth
Aid in prehension and particle reduction
Tongue
Prehension, mixing and tasting
Salivary glands
Produce saliva that it is composed of mucin, bicarbonate, and urea with water
Esophagus
Carries food from the pharynx to stomach. Also aids the returning food to the mouth during regurgitation
Reticulum
initiates regurgitation. Looks like honeycombs. Also called the hardware stomach
Rumen
Microbial fermentation of feed and absorption of volitale fatty acids. Looks like carpet because of the papillae
Omasum
Water absorption. looks like the pages of a book and feels like a stressball
Abomasum
Is the true stomach. Produces HCl, pepsinogen, intrinsic factor, gastrin, lysozyme and rennin to curdle milk. Stores mixes physical breakdown of food. initial digestion of proteins.
Greater Omentum
Overlays the stomach. Produce leukocytes
Esophageal Groove
Two folds that allow milk to bypass the rumen and reticulum
Liver
Produce plasma proteins, angiotensinogen, IGF-1, process nutrients, degrade toxins hormones and drugs, also produce bile
Gall bladder
Stores bile
Pancreas
Produce procarboxypetidase, chymotrypsinogen, pancreatic lipase, pancreatic amylase, trypsinogen, insulin and glucagon
Duodenum
Produce carboxypeptidase, aminopeptidase, maltase, lactase, and bicarbonate. Also receive chyme, pancreatic secretions, and bile
Jejunum
Absorption of amino acids, monosaccharides, calcium, and iron. Digestion of protein and carbohydrates
Ileum
Absorption of water, electrolytes, vitamin B12, and bile salts.
Cecum
Microbial fermentation of starch and some cellulose. Absorb volatile fatty acids, vitamins, and water.
Colon
Microbial Fermentation of starch and some cellulose
Rectum
Formation of droppings
Anus
External opening
