Respiratory System
- The nasal cavity is responsible for warming, moistening, and filtering air.

- The nasal conchae, also known as turbinate bones, function to increase the surface area of the nasal cavity for air to come into contact with the mucous membrane.
- The alae, or wings, of the external nose are part of the walls of the nostrils.
- The main function of the respiratory portion of the system is to facilitate the exchange of oxygen and carbon dioxide between the atmosphere and the bloodstream.
