Answer:
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair.
Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins.
The swallowed food is pushed into the esophagus, which connects the throat above with the stomach below.
A ringlike valve blocks the passage from the esophagus to the stomach, but as the chewed food approaches, the muscles around the ring relax and the food passes into the stomach.
The upper part of the stomach is a holding area.
Through the action of the stomach muscles, little bits at a time are pushed into the lower part of the stomach, where it mixes with liquids and stomach acid, and an enzyme that breaks down protein, digestive juices that further break the solid food into a liquid form.
Next, it passes slowly into the small intestine.
