Question 1
Which of the following is not a function of the digestive system?
- Production of gametes
- Reabsorption of water from waste
- Mechanical and chemical digestion of food
- Absorption of nutrients
Explanation: In the digestive system, food is broken apart mechanically (by the teeth), then chemically (by the stomach). Food then travels to the intestines, where nutrients are absorbed and water is removed from the gut tube, leaving only the waste. The waste is then eliminated from the body. Production of gametes is the function of the reproductive system, and does not take place in the digestive system.
