A cow's omasum helps absorb water from its food.

Definition

Noun: The third compartment of the stomach in a ruminant animal, such as a cow or sheep. It is characterized by having many folds or leaves and is involved in the further absorption of water and nutrients from digested food, after it has passed through the rumen and reticulum.

Usage

Examples

• In their anatomy lesson, the veterinary students studied the structure of the omasum.
• The omasum is sometimes colloquially called the "manyplies" or "book" stomach due to its folded, leaf-like structure.

Advanced Usage
