What does the heart do? Why does it beat? What is a pulse? Up until the 17th century, most believed that blood sloshed around the body like ocean tides. Then the English physician William Harvey showed the world that the heart is actually a pump, and that blood circulates throughout the body. This marked one of the greatest advances in the study of medicine.
