Nose, the prominent structure between the eyes that serves as the entrance to the respiratory tract and contains the olfactory organ. It provides air for respiration, serves the sense of smell, conditions the air by filtering, warming, and moistening it, and cleans itself of foreign debris extracted from inhalations.

The shape of one's nose is determined essentially by the genes. Big nostrils are thought to be an adaptation to warmer and wetter environments, where getting more air into the lungs is more important than warming or humidifying the inhaled air.

These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.

Function. The two nasal cavities condition the air to be received by the other areas of the respiratory tract. Owing to the large surface area provided by the nasal conchae (also known as turbinates), the air passing through the nasal cavity is warmed or cooled to within 1 degree of body temperature.

The nasal cavity functions to allow air to enter the respiratory system upon respiration. Structures within the cavity regulate the flow of air and particles it contains. The olfactory region of the nasal cavity regulates the sense of smell.

The nasal mucosa plays an important role in mediating immune responses to allergens and infectious particles which enter the nose. It helps prevent allergens and infections from invading the nasal cavity and spreading to other body structures, for example the lungs.

The nose and paranasal sinuses are part of the upper respiratory tract. The functions of the nose include the sense of smell and conditioning of inhaled air by warming it and making it more humid. Hairs inside the nose prevent large particles from entering the lungs.

Some animals have noses for smelling, and others use an organ that works like a nose to sniff or sense information. Animals can also release smells to send a message to other animals. A scent can be used to help find food, communicate, mark an animal's territory, find a mate, and keep away another animals.
