Study Notes
Functions of the Respiratory System
- Supplies the body with oxygen and removes carbon dioxide
- Maintains homeostasis and a normal pH
- Supports the body's immune system to fight infections
Anatomical Divisions
- Divided into the upper and lower respiratory airways
Functional Divisions
- Conducting portion: Transports gases
- Respiratory portion: Gas exchange
Conducting Portion
- Includes the upper and lower respiratory airways
- Contains:
- Nasal cavity
- Pharynx
- Larynx
- Trachea
- Extra pulmonary bronchi
- Intrapulmonary bronchi
- Bronchioles
- Terminal bronchioles
Diagram Summary
- The left section shows a simplified branching structure of the trachea, bronchi, and bronchioles leading to alveoli (the tiny air sacs).
- The right section presents a side view of the human head and upper chest, highlighting the different parts of the upper and lower respiratory tract (nasal cavity, pharynx, larynx, trachea, bronchi, and lungs).
- These diagrams depict the pathway of air through the system and where gas exchange occurs.
