which best describes the relationship between the circulatory system and the respiratory system?○ the circulatory system is the transport system for the respiratory system.○ the respiratory system is the transport system for the circulatory system.○ the circulatory system diffuses red blood cells into the respiratory system to pick up oxygen.○ the respiratory system transfers hemoglobin to the red blood cells of the circulatory system.

Answer

Brief Explanations:

The respiratory system facilitates gas exchange (taking in oxygen, releasing carbon dioxide), while the circulatory system (via blood) transports these gases to and from body cells. The circulatory system acts as the transport mechanism for the respiratory system's gases. The other options are incorrect: the respiratory system does not rely on the circulatory as its transport system, red blood cells are not diffused into the respiratory system, and hemoglobin is already in red blood cells, not transferred to them by the respiratory system.

Answer:

A. The circulatory system is the transport system for the respiratory system.
