About Lungs Biology
The lungs are organs of the respiratory system that allow us to take in and expel air. The body contains two lungs, of which one is positioned on the left side of chest cavity and the other on right side.The process of breathing in and out is known as ventilation. In the breathing process, the lungs take in oxygen from the air through inhalation. Carbondioxide produced by cellular respiration is in turn released through exhalation.
