The document discusses how smell and taste are connected. When you have a cold and your nose is stuffed up, you have trouble smelling and tasting because smell influences taste. Odors are made up of tiny molecules in the air that activate smell receptors in the nose. Taste comes from nerves on the tongue that detect flavors through taste buds, but smell plays a role too by enhancing flavors we taste.
