Question

when a person runs, their muscles need more oxygen. the heart begins to beat faster, and breathing becomes quicker. the blood carries more oxygen from the lungs to the muscles, and the waste gas carbon dioxide is carried back to the lungs to be exhaled. which statement best describes the interaction between body systems in this situation? the muscular system controls a. breathing rate while the circulatory system filters air. the circulatory and respiratory b. systems work together to deliver oxygen and remove carbon dioxide. the digestive system provides oxygen c. to the muscles for movement. the nervous system and immune

Explanation:

When a person runs, the heart (circulatory system) beats faster and breathing (respiratory system) becomes quicker. The blood (circulatory) carries oxygen from the lungs (respiratory) to muscles and carbon dioxide back to lungs (respiratory) to be exhaled. This shows the circulatory and respiratory systems working together.

• Option A: The nervous system (not muscular) controls breathing rate and the respiratory system (not circulatory) filters air. So A is wrong.
• Option B: As explained above, the circulatory (blood) and respiratory (lungs) systems work together for oxygen delivery and carbon dioxide removal. So B is correct.
• Option C: The respiratory (not digestive) system provides oxygen. Digestive system is for breaking down food. So C is wrong.

Answer:

B. The circulatory and respiratory systems work together to deliver oxygen and remove carbon dioxide.
