Introduction to the Heart
What do you think of when you see a heart: strong emotions of love and affection or the throbbing pulse in your neck?
When a biologist sees a heart, she thinks of the important biological functions that the heart performs. Although it is only a little bigger than a fist, the heart is capable of pumping enough blood to fill the gas tanks of 100 minivans each day. Each beat provides the organs within the body the oxygen and nutrients they need to function properly.
