Our noses perform important functions every day of our lives, but we often only notice when disease changes how they work.
Our sense of smell works when chemical molecules are sniffed into the nose and make contact with the sense organ called the “olfactory bulb” in the roof of the nasal cavity. The other main function of [the] nose is to warm and moisten air going to the lungs (air conditioning) and to remove unwanted particles and viruses suspended in the air (filtering).
