nostril
Definition
A nostril is one of the two openings in the nose that allow air to enter. The nostrils are located on the front of the nose and they are separated by the septum.
The nostrils are lined with a moist membrane that helps to filter the air that enters the nose. The membrane also contains tiny hairs that help to trap dust and dirt.
When we breathe in, the air passes through the nostrils and into the nasal cavity. The nasal cavity is where the air is warmed and humidified before it travels to the lungs.
The nostrils are important for breathing and for smell. They help to filter the air that we breathe in and they also help to trap odor molecules.
