Digestion and Absorption

Solution:

Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Small intestine of the human gut is the longest part of the digestive system. Due to its small diameter, it is called the small intestine. Its length is about $22$ feet in human. Such a length increases the scope of food absorption as it is the major site of digestion and absorption of different types of food.
