Answer:
Digestive System
Explanation:
The excretory system is responsible for getting rid of waste in the body, meaning it is not the correct answer. The circulatory/cardiovascular system pumps blood throughout the body and helps to transport gases, hormones, nutrients, and cellular waste too, meaning it too is not the answer. The muscular system is responsible for helping to create movements and maintain posture which makes it not the correct answer. Last but not least is the digestive system, which breaks down food into nutrients that can be absorbed and used to support the body, which makes this the correct answer.
