The classic five senses are sight, smell, hearing, taste, and touch. The organs that do these things are the eyes, nose, ears, tongue, and skin.
FUNCTIONS
Eyes obviously allow us to see. But if you break it down, they do more than just that. Using our eyes, we can judge depth, interpret new information, and identify color (the wavelengths of light that reflect off surfaces).
Noses are used to smell scents. They get a sense for what particles are traveling through the air, which can help us identify if dangerous chemicals are nearby. Smell also has the strongest connection to memory; a familiar smell can remind us of things long forgotten.
Tongues are used to taste foods, allowing us to figure out if something is going to be useful to our bodies or poisonous. They also allow us to sense hot and cold in food and liquids.
Last of all is the skin, which is responsible for what may be the most important senses in the human body. The skin performs a huge number of functions.
