Overview Of The Respiratory System

The primary function of the respiratory system is gas exchange—delivering oxygen (O2) from the environment to the tissues and removing carbon dioxide (CO2) from the tissues. Generally, the respiratory system acts as a servant to the rest of the body by delivering enough O2 and removing sufficient CO2 for metabolic demands. As O2 demand increases, the body responds with a variety of mechanisms to ensure an adequate supply of O2. These physiologic mechanisms include the unique functions of several cell types in the lung, pulmonary circulation, mechanics of the respiratory system, transport of O2 and CO2 in blood, respiratory gas exchange, and coordination of all of these mechanisms by the respiratory control system. Each of these topics is covered in subsequent chapters.

It is important that the respiratory system respond to changes in O2 supply. Many of the responses to changes in O2 supply are the same as those used to respond to changes in O2 demand. If the supply-and-demand relationship for O2 is disrupted by disease, then physical activity is limited and organ failure may occur. Diagnosing and treating respiratory disease requires understanding how the structure, function, and control of the respiratory system interact to match supply and demand at each step in the chain of O2 transport.
