To start off our human body project we did the heart. Here is some of what we did.


1. Your heart is the size your fist.
2. An adult's heart beats between 60 - 80 times a minute when they are resting.
3.You have 100,000km of blood vessels.
4.The heart of a new born baby beats 120 -160 times a minute.

In the picture above we are looking at how you blood goes in the heart one way and comes out the other.



Cause - Most heart attacks occur as a result of coronary artery disease (CAD). CAD is the buildup over time of a material called plaque on the inner walls of the coronary arteries. Eventually, a section of plaque can break open, causing a blood clot to form at the site. A heart attack occurs if the clot becomes large enough to cut off most or all of the blood flow through the artery.

4 ways to help prevent a heart attack

1. Eat a low fat healthy diet with lots of vegetables and fruit!

2. Lower your salt intake!

3. Quit smoking!

4. Do physical activities to improve your heart fitness!
