Rumen the large first compartment of the stomach of ruminant from which food is regurgitated for rumination
Reticulum the second compartment of the stomach of a ruminant in which folds of the mucous membrane form hexagonal cells
Omasum the third chamber of the ruminant stomach that is situated between the reticulum and the abomasum
Abomasum the fourth compartment of the ruminant stomach that follows the omasum and has a true digestive function
Salivary Gland any of various glands that discharge a fluid secretion and especially saliva into the mouth cavity
Gallbladder a membranous muscular sac in which bile from the liver is stored
Pancreas a large gland of the body that is near the stomach and that produces insulin and other substances that help the body digest food

Lleocecal Valve the valve formed by two folds of mucous membrane at the opening of the ileum into the large intestine
