HEARING TOUCH
Our skin is the organ we use to touch. It is the largest organ in the human body.
Our ears are the organs of hearing. Our skin can tell us if something feels soft or hard, hot or cold, rough or smooth. They are very delicate. Earwax (sticky substance) protects our ears from dirt and infection. Sensory nerves send this information to our brain.
