Situated in the center of the face, the nose has many important roles. When you inhale cold air, it takes the nose a quarter of a second to heat it up to around 95 degrees, a temperature appropriate for the human body. It also adjusts the humidity of inhaled air and purifies it by filtering out foreign particles.
The nose is also our organ of smell, and the nasal cavity is important for articulating consonant sounds like “m” and “n.”
