Blood
Our Elixir of Life
One moment of distraction and the damage is done: Tim has slipped and has scraped his knee. The wound begins to bleed. Back home, Tim is comforted by his mother and a plaster is put on the knee. Actually, this is not necessary any more because Tim’s body has already started to help itself by forming a scab on the wound. A skin injury makes it possible for germs and dirt to enter the body. To prevent this from happening our organism repels all foreign substances, beginning at the same time to close the wound. This is done with the help of blood clotting, which starts directly when blood gets into contact with the outside world for example.
