Question

In what way is the basic structure of the stomach of a cow different from the stomach of a human?

Answer 1

The stomach of cows is composed of four chambers unlike human stomach which has a single chamber. The food in cows is firstly introduced in the first chamber of the stomach called rumen. In rumen, partial digestion of food occurs and the partially digested food is called cud. Thereafter, it is passed to the second chamber, from where it is reintroduced into the mouth for proper chewing. Followed by proper chewing, the remaining chambers of the stomach carry out complete digestion of food.
