Let’s take a look at the

Heart at work

See the difference in the HEART ratewhen we are resting, in school, or

playing sports?

When we do not exercise or eat properly, we damage our heart.

Fatty foods can make the inside of ourBlood vessels narrow

This blocks blood flow

If blood cannot reach the heart, the HEART muscle begins to die

This causes a HEART ATTACKhttp://www.healthexpo.org/Bluit%20Cover.jpg Stille, Darlene R. pg 31

Do YouREMEMBER

What Veins & ArteriesAre?

BLOOD VESSELS

VEINS are blood vessels that carry used blood back to the heart.

The heart sends the blood back to the lungs to pick up more oxygen.
