The document summarizes key topics covered in Chapter 22 of the respiratory system review, including tracing airflow through the nasal passages into the alveoli, identifying the structures of the upper and lower respiratory tract, describing the function of pulmonary surfactant and gas transport, explaining the neural control of breathing and gas laws, and calculating pulmonary volumes and capacities. It also lists disorders of the respiratory system, structures of the lungs such as the bronchial system, muscles of respiration, and the role of atmospheric pressures and the pleural cavity in breathing.

2. Chapter 22 Respiratory System Review
IMPORTANT
This is not a comprehensive review. You are
responsible for all information in Chapter 22.

3. Chapter 22 Respiratory System
• Be able to trace air flow from nasal and oral passages into aveoli
• Beginning and end of nasal cavity
• Nasal concha
• Where the upper and lower respiratory tracts begin and end
• Cartilages of the respiratory system – trachea structure
• Function of pulmonary surfactant
• How Oxygen and Carbon dioxide are transported
• All pulmonary volumes and capacities
• Partial pressures and their amounts

4. Chapter 22 Respiratory System
• Terms – hemoglobin, partial pressures, atelectasis
• Neural control of breathing
• Pressure and airflow
• Gas Laws
• Variations in Respiratory rhythm
• Alveolar gas exchange (gas transport)
• Systemic gas exchange
• Disorders of the respiratory system
• Anatomical structures of the lungs

5. Chapter 22 Respiratory System
• Bronchial system
• Be able to calculate using pulmonary volumes and capacities. This
means you need to know how these volumes and capacities “fit”
together.
• Muscle of respiration
• Atmospheric pressures and it’s relationship to inhalation and
exhalation.
• Pleural cavity’s role in breathing/ventilation
