ANATOMY

Detailed explanation-1: -NT Rumination is the regurgitation of undigested food from the stomach back up into the mouth. It is a reflex response, not a conscious decision. Rumination is normal in cows; it is not a normal part of digestion in humans.

Detailed explanation-2: -Rumination or cud-chewing is the process by which the cow regurgitates previously consumed feed and chews it further.

Detailed explanation-3: -Overview. Rumination syndrome is a condition in which people repeatedly and unintentionally spit up (regurgitate) undigested or partially digested food from the stomach, rechew it, and then either reswallow it or spit it out.

Detailed explanation-4: -The unchewed food travels to the first two stomachs, the rumen and the reticulum, where it is stored until later. When the cow is full from this eating process, she rests. Later, the cow coughs up bits of the unchewed food called cud and chews it completely this time before swallowing it again.

Detailed explanation-5: -Cud is a portion of food that returns from a ruminant’s stomach to the mouth to be chewed for the second time. More precisely, it is a bolus of semi-degraded food regurgitated from the reticulorumen of a ruminant.
