Respiratory System Overview

The respiratory system is vital for gas exchange, allowing oxygen in and carbon dioxide out. Key components include:

1. Nose: Filters and moistens air.
2. Nasal Cavity: Conditions air and detects smells.
3. Pharynx: Connects respiratory and digestive pathways.
4. Larynx: Houses vocal cords and protects the trachea.
5. Trachea: Conducts air to the bronchi, lined with cilia.
6. Bronchi: Branches into each lung, further dividing into smaller passages.
7. Bronchioles: Lead to alveoli, where gas exchange occurs.
8. Lungs: Main organs for gas exchange, containing alveoli.
9. Diaphragm: Muscle that facilitates breathing by changing lung volume.

Together, these structures ensure efficient oxygen delivery and carbon dioxide removal.
