Understanding the structure and function of the lungs, along with the common respiratory diseases that affect them, underscores the importance of maintaining respiratory health

• relate the function of any portion of the respiratory tract to its gross and microscopic anatomy. The term respiration has three meanings: (1) ventilation of the lungs (breathing), (2) the exchange of gases between air and blood and between blood and tissue fluid, and (3) the use of oxygen in cellular metabolism.
