What is the term for the small protrusions in the nasal cavity that increase surface area?

The small protrusions in the nasal cavity that increase surface area are referred to as turbinates, also known as conchae. These structures are critical to the function of the nasal cavity, as they help to warm, humidify, and filter the air that enters the respiratory system. By increasing the surface area, turbinates allow for more efficient interaction between the air and the mucous membranes lining the nasal passages.

The dual terminology is appropriate because "turbinates" is a common term used in clinical settings, while "conchae" reflects the anatomical naming conventions. Both terms refer to the same structures and highlight their significance in respiratory physiology.

Understanding the function of turbinates/conchae helps emphasize their role in maintaining respiratory health, which is crucial for preventing infections and ensuring optimal air quality is delivered to the lungs.
