What is the function of the nose (in humans)?

The main function of the nose in humans is to smell, allowing us to detect and perceive various scents and odors in the environment. Additionally, the nose also serves the function of filtering and humidifying the air we breathe, as well as assisting in the process of tasting food by contributing to the sense of flavor. The nose also plays a role in breathing, helping to regulate airflow and maintain proper oxygen levels in the body.
