Respiratory System
• Primary functions:– Inspiration of oxygen
– Expiration of carbon dioxide
Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.
Respiratory System
• Movement of air:– Nasal and sinus passages
– Pharynx
– Trachea
– Bronchi
– Bronchioles
– Alveoli

Structures of the Respiratory System
Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.
Exchange of Gases
1. Oxygen diffuses through alveolar wall into surrounding capillaries
2. Hemoglobin transports oxygen to cells
3. Carbon dioxide moves from tissues into bloodstream
4. Carbon dioxide moves into alveoli and is exhaled
