Digestion is how your body turns food you eat into nutrients it uses for energy, growth, and cell repair. The digestive tract (or gastrointestinal tract) is a long twisting tube that starts at your mouth and ends at your anus.
Procedure::--
The churning action of the stomach muscles physically breaks down the food. The stomach releases acids and enzymes for the chemical breakdown of food. The enzyme pepsin is responsible for protein breakdown. The stomach releases food into the small intestine in a controlled and regulated manner.
