Just as a fire needs oxygen to burn, the human body also needs a continuous supply of this essential element for the process of combustion that goes on constantly in every cell. We ordinarily do not think of a body metabolism as combustion, yet that is what is: The job of the respiratory system is to furnish the oxygen that combines with these fuels in each of the billions of cells, and to carry away the waste product of carbon dioxide.

The exchange must take place in every cell, including those distant from the oxygen - rich atmosphere that surrounds us. Obtaining that oxygen and starting it on its all - important trip through the body begins with those critical organs, the page 2 lungs.

Normally there is no space between them, but entry of bacteria, penetrating wounds, or disease may separate the pleura.
