lungs
Now,i am going to talk about the lung.First of all i'm going to say that the lung is the most important organ in your respiratory system.You have two lungs sitting inside your chest,one in right side and one in left side.Your two lungs make one of the largest organs in your body.Your lungs are partners with your respiratory system,and the goal their trying to achieve is to allow you to breath in oxygen and breath out carbon dioxide. Your heart pumps blood into your lungs and your lungs absorb the oxygen and give out the carbon dioxide out. This is he basic definition of the function of your lungs.
