Respiratory System Structure and Function

• Describe the anatomical pathway of air through the respiratory system, tracking from the mouth and nose through the trachea, bronchi, bronchioles, and down to the alveoli. • Explain the specific role of the alveoli as the primary site for pulmonary gas exchange. • Understand the mechanics of breathing and the specific functional role of respiratory muscles, notably the diaphragm and intercostals. • Define key respiratory measurements, including breathing rate, tidal volume, and minute ventilation.
