question 1 of 5
exercise can help your heart and lungs, your bones, and your ______.
select a response below.
○ legs
○ muscles
○ arms
○ brain

Explanation:

Exercise is known to benefit multiple body systems. Muscles are directly impacted by exercise as it helps in muscle growth, strength, and endurance. Legs and arms are parts of the body, but the question is looking for a broader category that exercise benefits along with heart, lungs, and bones. Muscles are a key component that exercise helps, as it stimulates muscle fibers, improves muscle tone, and supports overall muscular health, which aligns with the benefits to heart (cardiovascular system), lungs (respiratory system), and bones (skeletal system).

Answer:

B. muscles
