In 2005, researchers followed the air through your nose, and were amazed by what they found; the human nose is more complex than a 747's after scientists created a transparent nose model to study airflow. The research showed how breathing changes the movement of air inside the nose and explained why deep inhalation helps detect faint smells. The findings may help doctors improve nasal treatments, surgery planning, and medicine delivery through the nose.
