Definition & Meaning of "omasum"

What is "omasum"?

The omasum is a chamber within the stomach of ruminant animals, located between the reticulum and abomasum. It serves as a crucial site for further digestion and absorption of nutrients. The omasum is characterized by numerous folds and papillae, which increase the surface area available for nutrient absorption. Its primary function is to remove excess water from the digesta and further break down plant material through mechanical action. The omasum plays a vital role in the overall digestive process of ruminants, contributing to the efficient extraction of nutrients from their plant-based diet.
