MCQ on Digestion and Absorption for NEET Pdf

Digestion is the process by which food is broken down into smaller nutrients, making it easier to absorb. Large insoluble molecules are broken down by digestive enzymes into smaller water-soluble molecules. In animals digestion occurs inside the body therefore, animal digestion is called internal digestion. Animals have a special organ system called the digestive system to complete the digestion of food. 

They store food in the digestive tract through the mouth. Inside the mouth both mechanical and chemical digestion of food takes place. Mechanical digestion is achieved by chewing. Food is chemically digested by the enzyme amylase present in saliva.
