The Five Senses: touch, hearing, smell, taste and sight 

  • The sense of touch allows you to identify characteristics of the objects around you. Your skin is the sense organ of touch. The skin has sensitive touch receptors that allow you to distinguish different sensations. 
  • Hearing is the sense you use to capture sounds. Ears are the sense organ of hearing. The ears capture sound vibrations and send them to the brain. The ear has three parts: the outer ear, the middle ear and the inner ear. The sense organ of smell is inside your nose. In order to smell, an odour must enter your nose through the nostrils and reach the nasal lining inside the nasal cavity where there are special smell receptors that capture the odour.
  • The sense of taste allows you to capture five different basic flavours (salty, sweet, bitter, sour and umami). The tongue is the main sense organ of taste. It is inside the mouth and it's covered with small bumps called taste buds. 
  • The sense of sight is used to distinguish shapes, colours, size and distance. The sense organ of sight is the eye.In order to see there must be light and the light must reach your eyes. First, light passes through the cornea and then through the pupil. The level of light is controlled by the iris, then it goes through the lens which help the eye to focus. Finally the retina captures light. This information is sent to the brain through the optic nerve. Now you are going to watch an interesting video about the five senses.
