During Inhalation the Oxygen enters the Alveoli of the lungs . The alveoli is surrounded by very tiny Blood vessels called Capillaries . Through Diffusion The O2 Moves out of the alveoli and into the Blood . Now the Blood carries it all over to the body with the help of Hemoglobin .The Blood Passes through Tissues then the O2 diffuses into the cells due to its higher concentration in the blood .The O2 Combines with the digested food present in the cells to give out Energy . So this is how O2 moves .
Hope This Helped
