Which system is responsible for digesting food and eliminating waste?

The Digestive System is the correct answer because it is specifically designed to break down food into nutrients that the body can absorb and utilize for energy, growth, and cellular repair. This system includes various organs such as the mouth, stomach, liver, and intestines, which work together to process food. Additionally, the Digestive System plays a critical role in the elimination of waste products from the body after the nutrients have been extracted, ensuring that the body efficiently discards what it does not need.

In contrast, the Musculoskeletal System is involved in supporting the body structure and enabling movement, while the Respiratory System is responsible for exchanging oxygen and carbon dioxide in the body. The Genito-Urinary System primarily deals with the reproductive functions and the regulation of waste removal through urine. Each of these systems has distinct roles that do not directly pertain to the digestion and waste elimination processes facilitated by the Digestive System.
