1. CV System Diseases

2. Atherosclerosis Inner lining of arteries become lined with plaque
Plaque – buildup of fatty substances
Think of water pipes freezing…Water is not able to get to where it needs to go!

3. Lets see what this looks like!
Atherosclerosis

4. Coronary Heart/Artery Disease
Greatest killer of all CV diseases! Leads to heart attack!
How a heart attack happens:
In order to function, the heart has to have oxygen, thus it needs blood!
Blood (and O2) are delivered to the heart via coronary arteries
When these arteries become clogged, O2 cannot reach the heart and a heart attack may occur!

6. Coronary Heart Disease…
Think of it like this…
Coronary arteries are like the power cords to the heart. When the power is interrupted, the heart does not function properly

7. CHD

8. Congestive Heart Failure
Your heart is a big muscle (cardiac muscle)
CHF occurs when your muscle becomes overworked, and lacks strength
Heart is not strong enough to pump blood to the rest of the body.
Blood pools and causes body tissues to swell! This causes the congestion!

9. Think of it like this…
A sump pump! If that pump doesn’t get the water out from your basement, it will pool, creating a mess!

10. Congestive Heart Failure
CHF

11. Stroke Your brain needs O2 also!!!
Stroke occurs when blood flow is interrupted to the brain
When O2 does not reach the brain, brain cells die
Mild strokes may cause dizziness, weakness, or numbness.
However serious strokes causes speech impairments, memory problems, and loss of motor control.

12. Strokes
Some strokes are so serious they can kill instantly

13. Stroke
stroke

14. Think of it like this…
Your brain needs blood (O2). When the power lines clog, the brain cannot work properly.

15. So… How do we avoid all these diseases!?
Avoid Tobacco!

Maintain Healthy Weight!
Exercise Regularly!
Manage Stress!
Aren’t you glad you have Health and PE!?!?!?!?
