Which system breaks down foods into nutrients and wastes?

Circulatory
Digestive
Integumentary
Metabolism

The correct answer is: Circulatory

The correct answer is the digestive system. The digestive system is responsible for breaking down foods into nutrients that can be absorbed by the body for energy, growth, and repair. It also helps in eliminating waste products from the body. The circulatory system, on the other hand, is responsible for transporting oxygen, nutrients, hormones, and other substances to and from the cells in the body. The integumentary system is the skin, hair, and nails, which function to protect the body from external factors. Metabolism refers to the chemical processes that occur within a living organism to maintain life.
