How does blood travel through your body?

The blood flows throught your body as a motion of a figure eight. The heart is located in the center and has two little loop like things crossing over it. The first loop the blood transfers from the heart then goes down to your lungs then back all the way to the heart. But the second one goes all around and through your body. But eventually it comes all the way back to the heart.There are a three blood vessels by your heart. The arteries, capillaries, and then veins. They are all helping the heart to make it be able to its job.

First is an arteries. They are muscular-walled tubes forming part of the circulation system by which blood is conveyed from the heart to all parts of the body. Next is the vein. It is a blood vessel that carries blood back to the heart. Last is the capillaries. They are vry tiny blood vessels where substances are exchanged between blood and body cells.

Why the Circulartory System is important?

It is because it has many functions that help the body work. It delievers materials,removes waste, regulates body temperature and fights disease. Blood takes away waste such as carbon dioxide from body cells. When it delievers materials, it transfers chemical messengers. When it removes waste, the blood takes away wastes from your body. When it regulates body temperature, changes in the amount of blood flow in the skin help carry heat away. And last is when it fights diesase, the blood contains cells that attack diesase causing microorganism.
