Question

which two body systems work to supply oxygen to the musculoskeletal system as you exercise?
○ respiratory and circulatory
○ circulatory and nervous
○ respiratory and digestive
○ nervous and digestive

Explanation:

To determine the two body systems that supply oxygen to the musculoskeletal system during exercise, we analyze each option:

• The respiratory system takes in oxygen from the air. The circulatory system (specifically the cardiovascular system) transports this oxygen - rich blood to the muscles (part of the musculoskeletal system).
• The nervous system is mainly for control and communication, not oxygen supply. The digestive system is for breaking down food, not oxygen transport. So the respiratory and circulatory systems work together to supply oxygen to the musculoskeletal system during exercise.

Answer:

A. Respiratory and circulatory
