Lungs are a pair of respiratory organs located in the chest cavity protected by rib cage. They are spongy elastic and are enclosed by two membranes called Pleura. Space between the two membranes of the Pleura is filled with fluid.Pleura protects the lungs from injury. Right lung is larger than the left lungs and it is made of three lobes while the left lung has only two lobes. A pipe like structure called Trachea carries the air from Nose through Neck, thoracic cavity and opens into two…
