1. The Cardiovascular System

2. The Cardiovascular System transports fluid throughout the body.

3. The Heart 3 layers of the heart – Endocardium – Mydocardium – Visceral 4 chambers of the heart – 2 Ventricles (discharge blood) – 2 Atria (receives blood from parts of body)

4. Blood Vessels Carry blood towards and away from the heart 3 types of blood vessels: – Arteries Take blood away from the heart – Capillaries Responsible for exchange of chemicals and water between tissue and blood – Veins Transport blood to the heart

5. Blood Blood carries oxygen and nutritive elements towards the body cells What makes up blood: – White Blood Cells – Red Blood Cells – Platelets – Plasma Hemoglobin – Protein with Iron – Helps RBC’s transport oxygen

6. Diseases of the Cardiovascular System

7. Leukemia Cancer of the blood cells Too many white blood cells Abnormal, non-functional Flu-like symptoms, weakness Acute: develops quickly Chronic: develops more slowly Can affect lymphoid or myeloid cells

8. Sickle Cell Anemia Red blood cells become sickle-shaped Cells clog vessels and body doesn’t get enough oxygen Inherited disease

9. Hypoglycemia Low blood sugar Fatigue, anxiety, headaches, shakiness

10. Cardiomyopathy Disfiguration of the heart Usually inherited Causes difficulty breathing, fatigue

11. Taking care of your Cardiovascular System Increase whole grains, fruit, and vegetable intake Exercise regularly Get plenty of sleep Cut down on fats and sweets Don’t use tobacco products
