Animal nutrition includes nutrient requirements, mode of intake of food and its utilisation in the body.

Animal Nutrition and Digestion in Human Beings
Animal Nutrition:
Animal nutrition involves the study of the dietary needs of animals to maintain health, growth, and reproduction. It includes the process of ingestion, digestion, absorption, and elimination of food. Proper nutrition is essential for animals to thrive and perform their physiological functions.
Digestion in Human Beings:
Digestion in human beings is a complex process that involves the breakdown of food into smaller molecules that can be absorbed and utilized by the body. It begins in the mouth with the mechanical and chemical breakdown of food through chewing and the action of saliva. The food then travels down the esophagus to the stomach, where it is further broken down by stomach acid and enzymes.
After leaving the stomach, food enters the small intestine, where most of the digestion and absorption of nutrients take place. Here, digestive enzymes from the pancreas and bile from the liver break down carbohydrates, proteins, and fats into their simplest forms. These nutrients are then absorbed through the walls of the small intestine into the bloodstream.
The remaining undigested food moves into the large intestine, where water and minerals are absorbed, and waste products are formed. The waste products are then eliminated from the body through the rectum and anus.
Proper nutrition and digestion are essential for maintaining overall health and well-being in human beings. A balanced diet that provides all the necessary nutrients in the right proportions is crucial for supporting the body's functions and preventing diseases.
