Breath of life

Description

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.
