Nutrition in Animals Notes

• The small intestine is highly coiled and is about 7.5 metres long.
• It receives secretions from the liver and the pancreas.
• Besides, its wall also secrete juices.

• The liver is a reddish brown gland situated in the upper part of the abdomen on the right side.

• The large intestine is wider and shorter than small intestine.
• It is about 1.5 metres in length.
• Its function is to absorb water and some salts from the undigested food material.

• Once the food reaches the large intestine, most digestion has already taken place.
• The main functions of the large intestine are to absorb water and form faecal matter to remove wastes from our body.

Assimilation:

• Some plant-eating animals like cows, goats, sheeps, etc. swallow large amount of food at a time.
• 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.
