When blood enters the lungs from the heart it travels trough very fine capillary beds and gets transferred via diffusion from the alveolar sacs into the actual capillary beds. After this occurs the blood is then pumped back into the heart and distributed to the rest of the body. This is the method of adequate respiration.
