Detailed explanation-1: -The omasum is a globe-shaped structure containing leaves of tissue (like pages in a book). It absorbs water and other substances from digestive contents. Feed material (ingesta) between the leaves will be drier than ingesta found in the other compartments.
Detailed explanation-2: -The omasum is the third chamber in the ruminant stomach. It lies within the intrathoracic part of the abdomen so cannot be palpated manually. Instead it is examined by ausculation. The omasum has biphasic contractions which squeeze fluid out of the food before allowing the ingesta to continue into the abomasum.
Detailed explanation-3: -Cattle have a highly developed, large omasum. Interior lining of the omasum, revealing the “many piles” tissue folds in an 8-week-old calf. The abomasum is the “true stomach” of a ruminant. It is the compartment that is most similar to a stomach in a nonruminant.
