Your senses are how your body discovers and understands the world around it. We all know the traditional five senses: touch, sight, taste, hearing and smell. But these five are just the beginning. Our incredible bodies may actually have more than twenty senses including hunger, thirst and knowing when to go to the toilet. In order for us to have senses, we need sensors to detect them. Sensors include our eyes, ears, nose, skin and tongue. Not to mention the other sensors, like our blood, bladder and large intestine!
