What is the main function of the Digestive System?

• A. Collection of waste
• B. Absorption of nutrients
• C. Gas exchange
• D. Hormone production

Answer: (B)

The main function of the digestive system is the absorption of nutrients. This process involves breaking down food into smaller molecules through mechanical and chemical digestion, allowing the body to extract essential nutrients like vitamins, minerals, proteins, carbohydrates, and fats. These nutrients are then absorbed through the walls of the intestines and transported into the bloodstream, where they can be delivered to cells throughout the body for energy, growth, and repair. While collecting waste is a function of the digestive system, it is a secondary action that occurs after the primary function of nutrient absorption. Gas exchange is primarily the role of the respiratory system, not the digestive system. Hormone production is also not central to the digestive process, even though some hormones may be involved in regulating digestion. Thus, the vital role of the digestive system in nutrient absorption highlights its significance in overall health and bodily function.
