How are materials transported through your body?
The circulatory system is made up of the heart, blood vessels, and blood. This system is also known as the cardiovascular. Your circulatory system is like a postal service for your body, with the blood cells bringing things to and from your body cells. Your heart is the most important muscular organ that is constantly pumping blood through your body.
