The alveoli in the lungs are coated with a moist film that dissolves air in the lungs. Oxygen diffuses across the thin epithelium of the alveoli sacs into the blood within the surrounding capillaries. Carbon dioxide also diffuses from the blood in the capillaries to the alveoli air sacs.The now oxygen rich blood is returned to the heart via the pulmonary veins. Carbon dioxide is expelled from the lungs by exhalation.he lungs are organs of the respiratory system that allow us to take in and expel air. In the breathing process, the lungs take in oxygen from the air through inhalation. Carbon dioxide produced by cellular respiration is in turn released through exhalation.
