Solution-  Small intestine  is a part of the digestive system and it is a long tube-like structure which functions for nutrient and water absorption.

The small intestine is divided into three parts namely duodenum, jejunum and ileum. 

The main function of the small intestine is to absorb digested nutrients and water.

  •  Inner wall of the small intestine has millions of tiny finger-like projections called villi which in turn possesses microvilli for better absorption.


  • The structure of villi increases the surface area for efficient nutrient absorption. 

  • These villi are composed of many capillaries that absorb the digested food and carry it to the bloodstream.
