The nose is the primary organ for our sense of smell and is also involved in the process of respiration. The nose consists of two nostrils, which lead into the nasal cavity. Inside the nasal cavity are tiny hairs called cilia, which help to filter out dust and other particles. The nasal cavity also contains the olfactory epithelium, which is responsible for detecting odors.
The nose is supported by bone and cartilage and is covered by skin. In addition to its sensory functions, the nose also plays a role in shaping the appearance of the face.
