In the process of respiration,the inhalation and exhalation happen at the same time.When we inhale,the air is forced into the lungs and the alveolus.In the alveolus,the partial pressure of the oxygen from the inhaled air is higher than the oxygen presented in blood capillaries.Hence,the oxygen gas diffuses into the blood capillaries by followed concentration gradient.The partial pressure of the carbon dioxide prsesented in blood capillaries is higher than the carbon dioxide in the inhaled air.As a result,carbon dioxide diffuses out from blood capillaries into the alveolus and then excrete to the environment through exhalation.
