why is the large intestine broad and the small intestine narrow.

Hi Bhavya,

 

Small intestine is narrow, but large in length to completely digest the food and absorb nutrients through vill in its inner walls.

Large intestine is broad but small in length to pass down undigested food through it and do some absorbtion. It also performs the function of storage of wastes before they are excreted from the body via the anus.
