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.

Turbinate, also known as nasal concha or nasal turbinate, refers to the structures located inside the nasal cavity. There are three pairs of turbinates: superior, middle, and inferior. These bony structures are covered with a mucous membrane and are responsible for filtering, humidifying, and warming the air we breathe. The turbinates also help to increase the surface area of the nasal cavity, allowing for better contact between the air and the nasal tissues. They play a crucial role in regulating airflow, directing it efficiently through the nasal passages. Variations in the size and shape of the turbinates can impact nasal breathing and contribute to conditions such as nasal congestion or allergies.
