Abstract

The lung is a remarkable organ exchanging oxygen and carbon dioxide across a surface area the size of a tennis court (1). It is also the portal of entry for numerous carcinogens. An adult inhales approximately 10,000 liters of air daily, exposing the airways and alveoli to the contaminants in each breath.
