Presentation Transcript

  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
