Chapter 22, Problem 9TYK
Summary Introduction
Introduction:
Breathing involves the flow of air inside and outside the lungs to carry out gas exchange between alveoli and blood. This process is mainly involved in carryingoxygen from the alveoli to the blood and to other tissue cells and expulsion of carbon dioxide from the blood to the alveoli and finally to atmospheric air.
