● Lungs are situated in the thoracic chamber which is anatomically an air-tight chamber.

● The thoracic chamber is formed dorsally by the vertebral column,ventrally by the sternum, laterally by the ribs and on the lower side by the dome-shaped diaphragm.

● The anatomical setup of lungs in thorax is such that any change in the volume of the thoracic cavity will be reflected in the lung (pulmonary) cavity.

● Such an arrangement is essential for breathing,as we cant directly alter the pulmonary volume

● Lungs are covered by a double layered pleura with pleural fluid between them.It reduces friction on the lung-surface. 

● Outer pleural membrane is in close contact with the thoracic lining Inner pleural membrane is in contact with the lung surface.
