The Circulatory System
It’s a muscle
It’s located a little to the left of the
middle of your chest, and it’s about
the size of your fist.
What does it do?
The heart pumps blood into
your body.
The blood provides your body
with oxygen and nutrients it
needs.

How to
Take Care
of the
Circulatory
System
Taking care of the circulatory system is very important.
If you smoke, your blood is thinner so you get less
oxygen. If you get a shortage of oxygen you won’t live
very long because your body needs a lot of oxygen. You
will also need a monthly check-up at the doctor’s office.
