Blood capillaries surround each alveolus and carbon dioxide moves from blood present in these capillaries to alveoli because the partial pressure of carbon dioxide is higher in blood capillaries than in alveoli and oxygen moves from alveoli to blood because the partial pressure of oxygen is higher in alveoli than blood.
