The heart is made of only a few parts, but they are vital to the operation of the organ. A pamphlet can help a student learn about the ventricles, valves, arteries and other components in this vital part of the body. There are pictures of the different valves as well as the chambers that the student can learn about. Colors are sometimes used to give details about which way the blood flows into and out of the heart so that students can get a better idea of the circulation.
