Study Notes
Respiratory System
- The nasal cavity warms, humidifies, and filters air, preparing it for gas exchange.
- The oropharynx and laryngopharynx are lined with stratified squamous epithelium.
- The vocal cords are housed in the larynx.
- The trachea conducts air into the lungs.
- Simple cuboidal epithelium lines the bronchioles.
- Respiratory bronchioles participate in gas exchange.
- Alveolar ducts are lined with simple squamous epithelium.
- The primary function of alveoli is gas exchange (oxygen absorption and carbon dioxide removal).
- Type II alveolar cells produce surfactant, reducing surface tension and facilitating gas exchange.
- Pulmonary capillaries facilitate gas exchange by allowing oxygen and carbon dioxide to diffuse.
- Type I alveolar cells are flat, thin, and cover most of the alveolar surface, facilitating gas exchange.

Description
Test your knowledge of the passages through which air passes from the exterior to the alveoli and the cells that line each of them. Learn about the histology of respiratory airways and the functions of nasal cavity and pharynx in the air passage process.
