What is "nostril"?
The nostril refers to each of the two openings in the nose that allow air to enter and exit the nasal cavity. They are located on either side of the nasal septum, which divides the nasal passage into two. Nostrils play a vital role in the respiratory system, enabling the inhalation and exhalation of air. They also help filter and humidify the air we breathe, capturing particles and pathogens before they reach the lungs. The size and shape of the nostrils can vary among individuals and can affect airflow and nasal function.
