Answer 1

Answer:

Egestion : The process by which undigested is eliminated from the body is called egestion.

Digestion : The process of converting complex food particles into simpler ones which can be easily absorbed by the bosy is called digestion.

Assimilation : The process in which absorbed food material is utilized by the body to provide energy and building material is called assimilation.

The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria

Saliva contains the enzyme amylase, also called ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine.
