The circulatory system is one of the organ systems that make up an organism.
It is made up of the heart, blood vessels, and blood.
Figure 4 shows a model of a human heart. Your heart is about the size of your
fist. It pumps and circulates blood to the different parts of the body through the blood
vessels.
Certain diseases affect the heart and cause it to function improperly. To learn more
about these diseases and what they do to the heart, interview relatives or neighbors who
have heart problems or who know of people who have the disease. You can also use the
internet and the library to read articles about how certain diseases affect the heart, its
parts, and the whole organism.
