Exchange of Gases
Exchange of Gases: Overview
This topic describes the exchange of gases during respiration. The primary site for the exchange of gases are the alveoli. It discusses the exchange of gases at the alveolus and the body tissues and the transport of oxygen and carbon dioxide.
Important Questions on Exchange of Gases
