Question

Ruminants such as cows and buffaloes swallow their food hurriedly and then sit restfully and chew their food. Can you reason why?

Answer 1

The grass eating animals such as cow, buffaloes, horse, etc swallow half chewed grass quickly and store it in a part of the stomach called rumen.

Here the food gets partially digested. The partially digested food is called $\textbf{cud}$ returns to the mouth in small lumps and us chewed, by the process called rumination.

Answer 2

Answer:

Ruminants such as cows and buffaloes swallow their food hurriedly and store it in part of the stomach called rumen. The cellulose of the food is digested here by the action of certain bacteria which are not present in humans.

Later, this partially digested food is returned to the buccal cavity of the animals in small lumps and animal chews it sitting restfully to complete the process of digestion. This process is called rumination. The thoroughly chewed cud is swallowed again to other compartment of stomach and then into small intestine for complete digestion and absorption.
