2. CVD is a disease that affects the heart or blood vessels (cardiovascular disease – CVD) “The Silent Killer”

The Cardiovascular System heart blood blood vessels arteries capillaries veins

3. Hypertension = High Blood Pressure due to sodium consumption or heredity or inactivity.

Systolic The pressure while the heart is beating, the first or top # Diastolic When the heart is resting between beats, the 2nd or bottom #

4. Reduce Hypertension Eat low salt diet Exercise regularly Low saturated fat diet High fiber diet Medication Family history

Hardening of the arteries due to smoking cigarettes. 5. Arteriosclerosis Hardening of the arteries due to smoking cigarettes.

6. Atherosclerosis Plaque accumulates on the artery walls due to inactivity and sedentary lifestyle.

Plasma Platelets Hemoglobin Veins Capillaries

Breast cancer will affect 1 in 8 American women. It kills more women in the U.S. than any cancer except lung cancer. Getting regular screening tests is the best way for women to lower the risk of dying from breast cancer. — American Cancer Society 2011-2012

23. Metastasis The spread of cancer from the point where it originated to other parts of the body

Over half of all cancers can be prevented!

24. Types of Cancers A. Lymphomas Immune System B. Leukemias Blood forming Organs C. Carcinomas Glands, body linings, skin, digestive tract, lungs D. Sarcomaas Connective tissues, bones, ligaments, muscles

25. Risk Factors for Cancer Tobacco Use STD’s Diet (30% of all cancer) Radiation Exposure Heredity, Gender, Age, Ethnicity
