2. How does the process of digestion begin?

Ans. The process of digestion begins in the mouth, where food is chewed and mixed with saliva. Saliva contains enzymes that start breaking down carbohydrates. This mixture is then swallowed and travels down the esophagus to the stomach.

3. What is the function of the stomach in digestion?

Ans. The stomach serves multiple functions in digestion. It mixes the food with gastric juices, which contain hydrochloric acid and enzymes that further break down proteins. The stomach also controls the release of partially digested food into the small intestine.

4. Why is the small intestine important for digestion?

Ans. The small intestine is vital for digestion because it is the primary site for nutrient absorption. It has tiny hair-like structures called villi that increase the surface area, allowing for efficient absorption of nutrients and minerals into the bloodstream.
