This program explains why
the body needs regular supplies of air and how it gets them. The camera
follows the process of breathing through the ultra-thin membrane of the lung
into the blood, showing how the varying demand for oxygen is met by the
exchange of information between the brain and the chest muscles and how the
body rids itself of carbon dioxide. (26 minutes)
