Nose and Sinuses

Healing the Nose and Sinuses

Anatomy and Physiology of the Nose and Sinuses


The mouth and nose channel air from the environment through a system of tubes in the lungs. Air goes through mucus-covered nasal cavity lines. This membrane traps germs and dust. Small openings (ostia) in the roof of the cavity make it possible to smell. Nose hair is located inside the nostrils, which also help filter dust and other particles.


The sinuses have a special connection to the lungs because the purpose of the sinuses is to filter and humidify air breathed in from the nostrils. The sinuses make voice enhancement possible.

The sinuses are four hollow cavities lined with a thin layer of tissue in the skull.

  1. Maxillary sinus cavity—Located in the cheekbones
  2. Frontal sinus cavity—Located in the forehead
  3. Ethmoid sinus cavity—Located between the eyes
  4. Sphenoid sinus cavity—Located behind the nasal cavity

(See shaded grey areas in illustration)

Only the nasopharynx allows for the passage of air and is a continuation of the nasal cavity. The other two tubes that begin at the rear of the nasal cavity and end at the larynx enables speech and the passage of food and fluids.
