explain the process of digestion in grass eating  animals?

 Cows, buffaloes and other grass-eating animals chew continuously even when they are not eating grass. This is because they quickly swallow the grass and store it in a separate part of the stomach called rumen. Here the food gets partially digested and is called cud. But later the cud returns to the mouth in small lumps and the animal chews it. This process is called rumination and these animals are called ruminants. The grass is rich in cellulose, a type of carbohydrate, which the other animals, including humans, cannot digest it. 
But the ruminants have a large sac-like structure between the small intestine and large intestine, and the cellulose of the food is digested here by the action of certain bacteria which are not present in humans.

The grass-eating animals quickly swallow the grass and store it in a part of the stomach called rumen. Later they returns the grass into the mouth and chaw it. The grass is rich in cellose, a type of carbohydrate. Many animals, including humans cannot digest cellulose. Ruminants have a large sac-like structure called Caecum between the small intestine and large intestine. The cellulose of the food is digested here by the action of certain bacteria which are not present in humans.



THIS WAS THE DIGESTIVE SYSTEM IN GRASS EATING ANIMALS. PLEASE LIKE MY ANSWER.

They feed on grass and leaves that contain a carbohydrate called cellulose that is only digested by some animals as they have a structure called Caecum .
They have a part called Rumen where the grass is stored . The food gets partially digested here and is known as Cud

after swallowing the food it first goes in the first and the largest chamber rumen here it is partially digested and is known as cud.

Now food enters second chamber or the reticulum

Now it bypasses the first two chambers and enters the third and the smallest chamber omasum

Now it enters the fourth chamber obamasum ..here some gastric or digestive juices are secreted ...which help in digestion and the process comes to an end

Now the undigested food is egested out of the body

The grass eating animals undergo the process of.rumination and such animals are called ruminants
