Lungs

Respiratory System

Our lung is a very important part of body that used for respiratory. Our lung, divides into two lobes and the right into three lobes. If we count the length of airways that our lung has, the lungs contain approximately 1500 miles or 2,400 km, and the total surface of lung is about 70 m square in adult. Our lungs indeed have a very wide surface.

Since its sucking air every time, the lung tends to get disease more easily than any other part of our body. But why lung based diseases always diagnose in late condition/stage? This question may questioned by many people.
