How does this occur? Poor Diet Sedentary Lifestyle!
2. Coronary Artery Disease (Heart Disease) Greatest killer of all CV diseases! Leads to heart attack! How a heart attack happens: ▫1. In order to function, the heart has to have oxygen, thus it needs blood! ▫2. Blood (and O2) are delivered to the heart via coronary arteries ▫3. When these arteries become clogged, O2 cannot reach the heart and a heart attack may occur!
PROBLEMS 5. VERICOSE VEINS - Swollen and enlarged veins caused by weak valves
Problems 6. Anemia: decrease in number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. 7. Hemophilia- blood does not clot
So… How do we avoid all these diseases!? Avoid Tobacco! Cut back on Saturated Fats and Cholesterol! Maintain Healthy Weight! Exercise Regularly!*** Manage Stress! Aren’t you glad you have Health and PE!?!?!?!?
Heart disease can be hereditary If your parents/grandparents had heart disease, you may be more likely to get it.
How can exercise help the heart? Exercise makes the heart more efficient! Exercise increases stroke volume – the amount of blood your heart pumps per contraction Exercises decreases resting heart rate – amount of times your heart beats per minute while resting. Exercise makes your heart’s life easier!!!
