The visible part of your nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the septal cartilage (which separates the nostrils) and top of the and lower lateral cartilages. On average the nose of a male is greater than that of a woman.
The nose has living room of specialised cells which can responsible for smelling (part of the olfactory system). Another function of the nose is the conditioning of inhaled air, warming it and that more wet. Hairs inside the nose prevent large particles from entering the lung area. Sneezing is usually caused by foreign particles irritating the nasal mucosa, but can more rarely be caused by sudden experience with bright light (called the photic sneeze reflex) or touching the external auditory canal. Sneezing can transmit infections, while it creates aerosols in the fact that droplets can harbour germs.
