The name of the true stomach of a ruminant animal?

The true stomach of a ruminant animal is called the abomasum. It is the fourth compartment in the ruminant digestive system, following the rumen, reticulum, and omasum. The abomasum functions similarly to a monogastric stomach, where gastric juices break down food before it moves into the intestines for further digestion and nutrient absorption.
