Have you ever wondered how smells get from their source all the way to your brain? Your sense of smell does more than just let you enjoy different aromas, and a loss in this ability can impact your quality of life. This animated video shows students how smells travel to the brain and explains their importance in daily life, like alerting people to dangers such as a gas leak, spoiled food, or a fire. The video also explores reasons for changes in a person’s sense of smell.
