Nostril
Each of the two openings of the nose, the place where nose rings and nose studs are worn.
Also: naris, nares
The nostrils open into the nasal cavity and are separated by the columella, a strip of tissue that sits above the septum. Their shape and width vary widely. The fleshy side of a nostril, the ala, is the most common place for a nose piercing: in much of India a stud or ring, the nath for brides, is worn here, traditionally on the left. The septum between the nostrils can be pierced too.
