how do the respiratory and circulatory systems work together to make gas exchange possible?
Answer
Brief Explanations:
The respiratory system takes in oxygen and expels carbon - dioxide. Oxygen enters the alveoli in the lungs. The circulatory system, specifically the blood in capillaries surrounding the alveoli, picks up oxygen and transports it to body cells. At the same time, carbon - dioxide from body cells is carried by the blood to the lungs, where it is exhaled by the respiratory system.
Answer:
The respiratory system facilitates gas exchange at the lungs, and the circulatory system transports gases to and from body cells to enable gas exchange throughout the body.
