The nose is a prominent part of the face that helps us breathe and smell. It is made up of bone and cartilage, giving it structure. The outer part, called the nostrils, allows air to enter, while the inside is lined with special cells that detect different scents. This ability to smell is important for enjoying food and recognizing dangers, like smoke or spoiled food. In addition to its role in breathing and smelling, the nose also helps filter out dust and other particles from the air we inhale. It warms and moistens the air before it reaches the lungs, making it easier for our bodies to use. The nose is essential for our overall health and well-being.
