In which way do the respiratory and the circulatory systems interact with each other to sustain life?

• The respiratory system takes in oxygen from the air that the circulatory system distributes throughout the body.

• The circulatory and respiratory systems do not usually interact.

• The circulatory system takes in oxygen from the air that the respiratory system distributes throughout the body.
