Question

The respiratory system allows for gas exchange to happen in the lungs. How does the respiratory system affect the cardiovascular system? The respiratory system supplies the carbon dioxide that the cardiovascular system transports to the different cells for the production of energy. The respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy. The cardiovascular system supplies the carbon dioxide that the respiratory system transports to the different cells for the production of energy. The cardiovascular system supplies the oxygen that the respiratory system transports to the different cells for the production of energy.

Answer 1

The answer is The respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy. 

When air enters the lungs (part of the respiratory system), it passes all way to the alveoli, the smallest functional units of the lung. There, oxygen from the air enters the capillaries, the smallest blood vessels, next to the alveoli. Once in the blood stream, the cardiovascular system transports oxygen to different cells where it is used for the energy production.
