Nostrils are one of the ways that air is taken into the lungs, it is just through the nose rather than the mouth. Hairs in your nostrils filter dirt from the air. Air taken in through the nostrils also passes by smell receptors (olfactory receptors), which allows you to get chemical information about your environment.

The alar cartilage is a small, flexible structure located in the nose, specifically at the tip of the nasal septum and surrounding the nostrils. Its primary function is to provide shape and support to the external nose, helping to maintain its structure and allowing for the proper functioning of the nostrils during breathing. Additionally, the alar cartilage plays a role in facilitating the movement of the nostrils, which can aid in airflow regulation and enhance the sense of smell.
Cilia in the nostrils help to trap and filter out particles like dust, pollen, and bacteria from entering the respiratory system. They also help to sweep mucus and trapped particles towards the throat where they can be expelled or swallowed.
