👃 A facial feature located centrally on the face, the nose is an organ responsible for the sense of smell and plays a crucial role in the respiratory system. It protrudes from the face and consists of cartilage and bone, with two nostrils that allow air to enter and exit. The nose also aids in filtering, warming, and humidifying the air we breathe. Additionally, it contributes to our overall facial appearance, with various shapes and sizes adding to the uniqueness of each individual.
