Study Notes
Respiratory System
- The trachea is prevented from collapsing by C-shaped rings of cartilage.
- Olfactory receptors are responsible for olfaction (smell).
- The nasal septum divides the nasal cavities into right and left cavities.
- The primary function of the nasal cavities is to warm, humidify, and filter air.
- Diaphragm contraction and relaxation increases and decreases the chest's capacity during ventilation.
