They are supported by the surrounding lung tissue. The lungs are slightly different on each side. The right lung is divided into 3 sections called the upper, middle and lower lobes. The left lung is divided into 2 sections called the upper and lower lobes.
The covering of both the lungs is called Pleura. Anatomy: The pleura is a two layered structure namely the parietal and the visceral layers.The parietal layer lines the walls of the bony cage in the thorax and the upper surface of the big muscle called diaphragm that divides the chest cavity and the abdominal cavity.he covering of both the lungs is called Pleura.
