The skin is our largest organ and is essential for keeping us protected from invasion by harmful bacteria and controlling our body temperature. We judge whether people are scared or are in love by changes in blood flow through their skin. We see people getting old by the wrinkles in their skin. Some people, unfortunately, get skin cancer, often as a result of too much exposure to ultra-violet light from the sun. In this title, we will investigate what skin is, how it grows and how it protects us. Keeping warm is vital for the human body. The skin plays an important role in achieving a constant body temperature through sweating and regulating the blood vessels under the skin's surface. The reason for temperature regulation is to ensure that enzymes work properly. This title will also review that enzyme action.
