Nostril

A nostril is either of the two openings in the nose, serving as the entrance to the nasal passages. These openings allow air to enter and exit the respiratory system, facilitating breathing and the sense of smell. The inner surfaces of the nostrils are lined with mucous membranes and tiny hairs (cilia) that trap dust, pollen, and other particles, acting as a primary defense mechanism for the lungs. The shape and size of nostrils vary considerably between individuals and are influenced by genetic factors and ethnicity. Proper nostril function is essential for healthy respiration, and any obstruction can lead to breathing difficulties and affect the sense of smell. The skin around the nostrils is often sensitive and prone to irritation from environmental factors.
