The 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.The lungs are also closely associated with the cardiovascular system as they are the sites for gas exchange between the air and the blood.he now oxygen rich blood is returned to the heart via the pulmonary veins. Carbon dioxide is expelled from the lungs by exhalation. Air is supplied to the lungs through the process of breathing. The diaphragm plays a key role in breathing.
