Study Notes
Respiratory System
- The main function of alveoli in the lungs is to facilitate gas exchange between the lungs and the bloodstream.
Respiratory Epithelium
- The primary cell type lining most of the conducting portion of the respiratory system is ciliated pseudostratified columnar epithelial cells.
Conducting Portion of the Respiratory System
- Alveoli are NOT part of the conducting portion of the respiratory system.
Ciliated Columnar Cells
- The main function of ciliated columnar cells in the respiratory epithelium is to move mucus and debris out of the respiratory tract through the beating of their cilia.
Basal Bodies
- The function of basal bodies in ciliated columnar cells is to organize and anchor the microtubules of the cilia.
Test your knowledge of the anatomy of the respiratory system, including the conducting and respiratory portions, alveoli, and gas exchange. Learn about the structure and function of the respiratory system.
