Question

nervous
excretory
circulatory
muscular
pushes food through organs

Explanation:

To determine which system pushes food through organs, we analyze the functions of each system:

• Nervous: Controls and coordinates, not food movement.
• Excretory: Removes waste, not food movement.
• Circulatory: Transports blood, not food.
• Muscular: Smooth muscles in the digestive tract contract to move food (peristalsis). So the Muscular system (blue box) is correct.

Answer:

Muscular (the blue - colored box labeled "Muscular")
