  1. Go With The Flow – The Heart

  2. Blood

  3. Components of Blood • Blood is actually made up of several things. • Red Blood Cells • White Blood Cells • Plasma • Platelets

  4. Your Blood is made of • Plasma • Liquid part of blood • Pale yellow mixture of water, proteins and salts • Red Blood Cell • They carry oxygen to all parts of the body. • Remove Carbon Dioxide. • Remove other wastes. Red Blood Cells

  5. White Blood Cells • White Blood Cells • Fight and kill germs that may enter your bloodstream White Blood Cells act as cops patrolling the bloodstream White blood cell attacking an infection

  6. Platelets • Platelets • Form “scabs” when you cut yourself • Helps stop the bleeding Platelets surrounding a Red Blood Cell. A large scab

  7. Blood Types • Not all blood is the same. • Structures on the surface of blood can differ because of your genetic makeup. • Currently Scientists have grouped these structures into 8 different blood types. Percentage of blood types worldwide

  8. Percentage Blood Types - Australia

  9. What Blood Type Can Donate Blood to Me?** What Blood Type Can Donate Blood to Me?** Blood Transfusions Blood Transfusion Recent research suggests that this blood compatibility chart may change in the future as our understanding of blood improves. ** NOTE: Recent Blood research indicates that where, at one time, a person with type O negative Blood was considered to be a 'universal donor,' this may no longer be correct, because of a better understanding of the complex issues of immune reactions related to incompatible donor Blood cells. ** NOTE: Recent Blood research indicates that where, at one time, a person with type O negative Blood was considered to be a 'universal donor,' this may no longer be correct, because of a better understanding of the complex issues of immune reactions related to incompatible donor Blood cells.

  10. Blood Incompatibility When incompatibility blood mixes it clumps together, this can be fatal!

  11. Blood Vessels

  12. 3 Major Parts of the Circulatory system • Blood Vessels – routes for blood to travel • Heart – pumps or pushes blood through body • Blood – carries oxygen and nutrients through the body

  13. Blood Vessels - Overview • Your body resembles a large roadmap, There are “routes” or Blood vessels that take you blood to the heart and the rest of your body. • There are 3 types of blood vessels: • Arteries • Capillaries • Veins

  14. Blood Vessels - Detail • Arteries: The largest and thickest of the blood vessels. • Carry blood away from the heart to all the cells in the body. • Capillaries: the smallest blood vessels. • The exchange of oxygen and carbon dioxide take place in capillaries. • Bring blood to all tissue in the body. • Veins: Carry blood back to the heart.

  15. Clogged Blood Vessels If you eat too much fatty foods this is what happens to your blood vessels! Fat deposits in a blood vessel. A clogged blood vessel

  16. Heart Attack When the blood vessels of the heart are blocked it can cause a heart attack!

  17. Causes of blocked blood vessels • High blood cholesterol (too much fat) • Smoking • Physical activity • Obesity • Diabetes • Stress and anger Obesity

  18. The Heart

  19. The Heart • The heart is a vital organ that basically serves as a pump. • The heart pumps blood around the body. • To do this the heart is made up of a special kind of muscle tissue. • This muscle tissue allows the heart to beat constantly.

  20. Blood Flow - Basic

  21. Blood Flow – Advanced Order of Blood Flow • Superior Vena Cava • Right Atrium • Tricuspid Valve • Right Ventricle • Pulmonary Valve • Pulmonary Arteries • Lungs • Pulmonary Veins • Left Atrium • Bicuspid Valve/Mitral valve • Left Ventricle • Aortic Valve • Aorta • Body Tissue

  22. Order of blood flow Without oxygen - veins With oxygen - arteries
