Lungs: Respiratory System

Posted on

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 the chest cavity and the other on the right side. The right lung is separated into three divisions or lobes, while the left lung contains two lobes. Each lung is surrounded by a two-layered membrane lining (pleura) that attaches the lungs to the chest cavity. The membrane layers of the pleura are separated by a space filled with fluid.
