Internally, the pathway leads past the nasal vestibule, a region lined with coarse hairs (vibrissae) and sebaceous glands, and into the nasal cavity proper. One nostril may be slightly more congested or have higher airflow than the other at any given time.
Understanding the Function and Structure of Nostrils
This variation, known as the nasal cycle, helps optimize air filtration and moisture retention by alternating the dominance of airflow between the left and right passages throughout the day. Because they are exposed to the external environment, the nostrils are susceptible to a variety of conditions.
Each nostril forms a distinct inlet that channels air and scent molecules into the complex internal architecture of the respiratory and olfactory systems. This variation, known as the nasal cycle, helps optimize air filtration and moisture retention by alternating the dominance of airflow between the left and right passages throughout the day.
