The respiratory system and the circulatory system are closely related. While inhaling we take in air, the alveoli has less concentration of oxygen and greater concentration of carbon dioxide.
So the oxygen diffuses through the surface of alveoli . Where they mix with the blood. The hemoglobin has great affinity to oxygen so it attaches oxygen to hemoglobin and gets mixed to the blood. Where the blood vessels supply this oxygen rich blood to the heart.
Hope this is useful mark me as the brainliest if you are satisfied.
