CirculatoryIsaiTo

Blood moves through your body because veins put blood into the heart and arteries take blood out of the heart. These ways are keeping you alive. I will explain it more in the next paragraph that I will be talking about.

How blood flows through body
There are two loops in the heart. Blood travels from the heart to the lungs and then back to the heart in the first loop. Blood travels from the heart throughout the body and back to the heart in the second loop. Arteries, veins, and capillaries are three kinds of blood vessels. They also help blood flow through the body.

**The importance of the cardiovascular system**
The cardiovascular system is important because it fights disease, removes waste, and delivers needed substances to the cells that need it. Each of those is very important because they keep you alive.
