What is the purpose of the nose?

The purpose of the nose is to warm, clean, and humidify the air you breathe as well as help you to smell and taste. A normal person will produce about two quarts of fluid each day (mucus), which aids in keeping the respiratory tract clean and moist. Tiny microscopic hairs (cilia) line the surfaces of the nasal cavity, helping to brush away particles. Eventually the mucus blanket is moved to the back of the throat where it is unconsciously swallowed. This entire process is closely regulated by several body systems.

Structurally, the nose is separated into two passageways (left and right nostrils) by a structure called the septum. Protruding into each breathing passage are bony projections, called turbinates, which help to increase the surface area of the inside of the nose. There are three turbinates on each side of the nose (inferior or lower turbinates, middle turbinates, superior or upper turbinates). The sinuses are four paired, air-filled chambers which empty into the nasal cavity. Their purpose is not really known, but may help to lighten the skull, reducing its weight.

What are rhinitis and post-nasal drip?

Rhinitis is a very common condition and has many different causes. Basically, rhinitis may be defined as inflammation of the inner lining of the nose. More specifically speaking, it may be defined by the presence of one or more of the following symptoms:

• Rhinorrhea (runny nose)
  
  
• Nasal itching
  
  
• Nasal congestion
  
  
• Sneezing

Post-nasal drip is mucus accumulation in the back of the nose and throat leading to, or giving the sensation of, mucus dripping downward from the back of the nose. One of the most common characteristics of chronic rhinitis is post-nasal drip. Post-nasal drip may lead to chronic sore throat or chronic cough. Post-nasal drip can be caused by excessive or thick secretions, or impairment in the normal clearance of mucus from the nose and throat.
