Explanation

The lungs are enclosed by a double-layered thin membrane known as the pleura. This membrane provides protection and reduces friction during breathing. The diaphragm is a muscle that aids in respiration, the pericardium surrounds the heart, and the rib cage is the bony structure protecting the thoracic organs.
