Nose

The nose is an essential part of our respiratory system and sense of smell. It functions as the entry point for air when we breathe, filtering, warming, and humidifying it to protect our lungs. The nose contains tiny hairs and mucus that trap dust, germs, and other particles. Additionally, it houses sensory receptors for detecting odors, which contribute to our sense of smell and taste. Beyond respiration, the nose also plays a role in speech and facial expression. Its structure includes bones, cartilage, and mucous membranes, making it a vital organ for breathing, sensing, and communication.
