Ruminants such as cows and buffaloes swallow their food hurriedly and then sit restfully and chew their food. Give reason. [NCERT Examplar; HOTS]
Answers
Cattle are ruminant animals, this mean their stomach contains four compartments:
1. Rumen
2. Reticulum
3. Omasum
4. Abomasum
When a cow first takes food, it chews hurridly just enough to moisten the food. Once swallowed, the food goes the rumen, where it mixes with other acidic digestive liquids and is softened. The softened food is called cud, small balls of food.
Then the rumen muscles send the cud back up to the cow’s mouth, where it is re-chewed and swallowed again, and rechewed cud goes to the Omasum of stomach in order to take out all of the moisture.
Finally, the food enters the Abomasum of the stomach where it mixes with digestive juices and makes its way to the intestine to be completely digested.
Methanogenic bacteria are also present in digestive system of ruminants. They help in digestion of cellulose.
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.
