Rumen
Largest compartment of the ruminant stomach, where fermentation takes place (the process of breaking down organic compounds into simpler substances), larger ingesta
Reticulum

Pair of sacs between the internal and external anal sphincters. Walls are lined with glands that secrete a malodorous material (territorial marking)
Anus
Opening from the GI tract to the outside of the body
Bile

Bolus
Rounded mass of food (in the case of pharmaceuticals it refers to the preparation ready to be swallowed
Bowel
Intestine
Cecum
