These chemical senses inform us about the availability of foods and their potential pleasure or danger. Smell and taste also initiate physiological changes required for the digestion and utilization of food. In many animals, the olfactory system also serves an important social function by detecting pheromones that elicit innate behavioral or physiological responses.
