The nose helps us smell, taste, and breathe. This video investigates the olfactory organs, as well as the importance of the nose in the respiratory system and our sense of taste. An animated sequence takes viewers through the olfactory system step-by-step, including illustrations of the parts of the nose, the nasal cavity, and the palate. Physicians discuss the molecular structure of odors and how the brain interprets smells, and scientists compare the human sense of smell to that of other animals. 23 minutes. © 2001.
