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 because the movement of air inside the nose follows a path that is far more detailed than expected. Scientists created a transparent three-dimensional model of the human nose to observe how air behaves during normal breathing and rapid sniffing. Their work explained why people sometimes need to inhale deeply to detect faint smells. The study also suggested that a better understanding of airflow inside the nose could improve nasal surgery, medicine delivery, and treatment for blocked nasal passages.
