Digestion is a complex process that occurs in our body to break down food into simpler molecules that can be absorbed and utilized by cells for energy, growth, and repair. It involves both mechanical and chemical processes and occurs through a series of steps in different organs of the digestive system.
The process of digestion begins in the mouth. Mechanical digestion takes place as the teeth grind and chew the food, breaking it into smaller pieces. Chemical digestion begins with the action of saliva, which contains enzymes like amylase that start the breakdown of carbohydrates.
