Nasal refers to the nose. The nasal cavity is the air passage starting at the nostril (opening of the nose) and ending at the back of the throat. Nasal Obstruction is a partial or complete blockage of one or both of these air passages.
Allergic rhinitis is an allergy reaction affecting the lining of the nose that may be due to any one of several million different pollens, microscopic animals such as the house dust mite, skin scale or hair particles from animals.
The purpose of the nose is to warm and humidify the air that we breathe in. The nose is lined with many blood vessels that lie close to the surface and is situated in a vulnerable position as it protrudes on the face. As a result, trauma to the face can cause nasal injury and bleeding.
