Lungs Design And Purpose Index

Featured: Lungs Design And Purpose Main Article
The lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs. There are many diseases of the lung(s) to include: bronchitis, pneumonia, ARDS, COPD, emphysema, lung cancer, pleurisy, asthma, and tuberculosis.
