Summary Introduction
Introduction:
Breathing is the movement of air from outside the body through the bronchial tree and into the alveoli and the reversal of this air movement allow gas exchange between air and blood. The cause for these movements is the change in the size of the thoracic cavity that result from skeletal muscle contractions.
