Answer 2

In the process of digestion, the food is first chewed and then swallowed slowly. After swallowing the food from the mouth, it goes to the trachea (food pipe) in the food pipe there are peristaltic movements (pushing inward) which helps us to take the food to the stomach. In the stomach, HCL(hydrochloric acid) and many enzymes are used to digest the food. Form. There it goes to the small intestine where the absorption of useful nutrients takes place. After absorption in small intestine, the fodder goes into the large intestine. There the remaining useful nutrients and water are being absorbed. After the fully absorbed food passes through intestine to anus in which it is stored called as faeces. Then the faeces are excreted out of our body.
