The lungs are the largest organ of the respiratory system. The respiratory system supplies the oxygen needed by the cells of the body and takes away the waste carbon dioxide. Air is taken in through the nose and mouth and down the airway (the trachea or windpipe) into the lungs where oxygen is exchanged for carbon dioxide from the body’s tissues. The carbon dioxide is then exhaled out of the lungs and out of the mouth or nose. Refer this link to know more: http://www.mydr.com.au/respiratory-health/lungs-and-breathing
