=========================================

Nutrition in human beings is the process of intake of essential nutrients in the form of food.
It takes place through human digestive system.

Digestion is a catabolic process, in which complex and large components of food are broken down into their respective simpler and smaller forms with the help of various hydrolytic enzymes. These simpler forms are further taken up by different parts of body and are finally absorbed.


The entire system, which performs this process of digestion is known as digestive system. In human beings, the digestive system constitutes a long tubular structure called alimentary canal and digestive glands associated with it which secrete various digestive enzymes.
