Nose

Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration in conjunction with the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face; on most other mammals, it is on the upper tip of the snout.

Famous quotes containing the word nose:

    If you pick up some paint with your brush and make somebody’s nose with it, this is rather ridiculous when you think of it, theoretically or philosophically. It’s really absurd to make an image, like a human image, with paint, today.
    Willem De Kooning (b. 1904)

    And that laugh that wrinkles your nose touches my foolish heart.
    Dorothy Fields (1904–1974)

    There is no such thing as a perfect leader either in the past or present, in China or elsewhere. If there is one, he is only pretending, like a pig inserting scallions into its nose in an effort to look like an elephant.
    Liu Shao-Ch’I (b. 1898)
