Although skin is a waterproof structure, a few chemicals are able to pass through the tissues of the skin. When a person places a finger in a solution of one of these chemicals, it is possible for that chemical to enter the circulatory system and be carried to the tongue. The person then experiences the sensation of taste. Describe the pathway followed by this particular chemical from the finger until it reaches the tongue. Describe the part played by the nervous system to enable the person to experience the sensation of taste.
