• during exercise, the amount of O2 needed by muscles and CO2 produced increases
• This results in physiologic responses from heart and lungs
• the heart: increase heart rate, peripheral vasodilation, stroke volume to increase cardiac output
• the lung: increase tidal volume, respiratory rate to increase ventilation¹
