A giraffe's long neck needs a powerful heart to pump blood all the way to its head. Its blood pressure is about twice a human's, and special valves in the legs stop blood from rushing to the brain when it bends down. Giraffes drink for only a few minutes, then lift their heads slowly. Nature gave giraffes a clever circulatory system
