Detailed explanation-1: -Most ruminants have a four-chambered stomach and two-toed feet. The upper incisors are reduced or sometimes absent. Camels and chevrotains, however, have a three-chambered stomach and are often referred to as pseudoruminants. Ruminants eat quickly.

Detailed explanation-2: -The ruminant stomach has four compartments: rumen, reticulum, omasum, and abomasum. The abomasum is the true stomach where the cow’s own enzymes and acids break down the ingested feed. Rumination is the process by which the cow regurgitates previously consumed feed and masticates it a second time.

Detailed explanation-3: -The cow has four stomachs and undergoes a special digestive process to break down the tough and coarse food it eats. When the cow first eats, it chews the food just enough to swallow it. The unchewed food travels to the first two stomachs, the rumen and the reticulum, where it is stored until later.

Detailed explanation-4: -Actually all animals have just one stomach it may be divided into parts that perform different digestive functions. Ruminants those animals that “chew their cud” or burp and digest some more typically have 4 parts to their stomachs. There are no animals with 7 parts to their stomachs.
