We need a circulatory system to transfer heat around the body to keep our temperature constant; to provide pressure; and to transport substances to and from our tissues. This perfectly formed, intricate system makes sure our blood is sent to the right places, at the right time, in the right direction! In this title you'll learn what our circulatory system is made up of, why we need one, and the features that make it effective at carrying our blood around the body. We'll describe the structure and function of the heart, together with the effects of coronary heart disease, and how to lower your risk of suffering from it. You'll learn about blood: what it's made of, how it helps us fight disease, how it clots, and what happens when this doesn't take place properly.
