Abstract

Respiration is unquestionably a vital function of the human body, by which the oxygen available in the air is driven into the lungs where it reaches the blood and then carried to the cells everywhere in the body. It is also in the lungs that the gaseous product of the cellular combustion process (mainly CO2) gets transferred from the blood to the atmosphere. The understanding of the lung gas transport process is fundamental for prevention, diagnostics and therapy of many respiratory and cardiopulmonary diseases, e.g. hypoxemia, pulmonary sarcoidosis, fibrosis, cancer, asthma and emphysema.
