WONDER QUESTION: How does a human move?
 * A human brain sends a shock to a body part's muscle.
 * The brain sends the shock by a motor in our brain.
 * The muscle reads the shock and does it right away.
 * The heart helps us move by sending blood through our veins to keep us going.
 * A human makes blood in the bone marrow.
 * Monkeys are the closest animal to man.
