    • Anatomy
      The science dealing with the structure of animals and plants
    • William Harvey
      • Studied medicine at the University of Cambridge and at a famous medical school in Padua, Italy, during the Renaissance
      • Was interested in anatomy
      • Became a lecturer in anatomy
      • Was a doctor to Charles I
    • Galen's ideas

      Blood was made in the liver and then pumped around the body
    • Harvey proved Galen's ideas were wrong
    • Valves
      Devices that allow movement in one direction
    • Harvey proved the veins of the body contained valves
    • Harvey's experiments
      1. Dissecting human corpses
      2. Carefully observing the heart
      3. Dissecting cold-blooded animals, such as frogs
      4. Measuring blood flow
    • Corpse
      A dead body
    • Dissection
      The action of cutting apart the body of an animal or plant to examine its internal structure
    • In 1628, Harvey published his discovery in a book called An Anatomical Account of the Motion of the Heart and Blood
    • Harvey's discovery
      • The heart acts as a pump, moving blood around the body
    • Mechanical
      Operated by machinery
    • Mechanical water pumps used by firefighters in the 17th century may have given Harvey the idea that blood is pumped around the body by the heart</b>
    • Harvey was unable to explain how blood moves from the arteries to the veins
    • Microscope
      A scientific instrument that uses a magnifying lens to allow observation of objects too small to be viewed by the naked eye
    • Marcello Malpighi used one of the first effective microscopes to discover tiny blood vessels that carry blood from the arteries to the veins, which we call capillaries
    • Capillaries
      Tiny blood vessels linking arteries to veins
    • Microscopes were a key technological development in the Renaissance that transformed medical knowledge
