The Nose
|
|
Even though the front of the nose doesn't contain the olfactory organ that enables the sense of smell, it is a necessary part of respiration. The front of the nose filters, warms, and moistens air coming into the lungs. This means foreign debris is less likely to get caught inside the lungs.

Prosthetic Nose
|
|
The nose may be removed because of cancer surgery, traumatic amputation, burns, or birth defects. The prosthetic nose restores the normal appearance to the face, but it also has a practical purpose. It moisturizes the air coming in through the nose and filters the debris out.
