RUMEN: a large sack, representing approximately 80% of the whole stomach, also known as blanket or flat tripe.

RETICULUM: a small sack linked to the rumen with a spongy appearance, with small crests shaped like hexagonal “cells”, also known as honeycomb tripe.

OMASUM: the third chamber and the last of the “pre-stomachs” formed of a sack with lots of flaps, also known as book tripe.

ABOMASUM: the actual stomach, better known as reed tripe.
