The Nose - Side View
The nose contains shelf-like structures called turbinates, which help trap particles entering the nasal passages. Material deposited in the nose is transported by ciliary action to the back of the throat in 10-15 minutes. Cold viruses are believed to be carried to the back of the throat where they are deposited in the area of the adenoid. The adenoid is a lymph gland structure that contains cells to which cold viruses attach.
