Smell

Smell is one of the most important and basic senses in animals and human beings. Some animals use the sense of smell to recognize their home territory, animals of their own kind, and other kinds of animals. They also use smell to find food and mates. The scientific term for smell is olfaction, and the system by which we smell is known as the olfactory system.
