Circulatory system

  1. 1.
  2. 2. <ul><li>3 Major Parts of The Circulatory System
  3. 3. Heart
  4. 4. Blood Vessel
  5. 5. Blood</li></li></ul><li><ul><li>The Heart</li></li></ul><li>Function of the Heart<br />Heart is located at the center of your chest slightly tilted to the left . Its function is to pump blood and keep the blood moving throughout the body . The heart beats about 3 billion times during an average lifetime . It is an organ about the size of your fist .<br />
  6. 6. <ul><li>Heart Chambers</li></li></ul><li><ul><li>4 Chambers of the Heart</li></ul>Right and Left Auricle-are responsible for receiving used blood coming from all parts of the body.Right and Left Ventricle-are the pumping chambers of the heart , It is one of two large chambers that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs<br />
  7. 7. <ul><li>Heartbeat</li></ul>Heartbeats occur in two stages:Systole and Diastole Stage,in systole stage the heart contracts,in diastole stage,the heart relax.This alternate relaxation and contraction is called CARDIAC CYCLE.<br />
  8. 8. <ul><li>The Blood</li></ul>The blood is the liquid medium that is constantly flowing throughout the body.It is referred to as the River of life.The blood transports water,oxygen,nutrients,salts,hormones and other substances that sustain life.<br />A young person has about a gallon of blood,while an adult human has about 5 to 6 liters of blood.<br />
  9. 9. Components of the Blood<br />Red Blood Cells (RBC)Erythrocytes are small , spherical <br />enucleated and biconcave cell. It trans--port gases (oxygen and carbon dioxide) respectively to and from cells.White Blood Cells (WBC)<br />Leukocytes are irregular in shape,and are slightly larger than the RBC.It fights bacteria and germs.<br />
  10. 10. Platelets<br />Thrombocytes are the smallest of the formed components of the blood. The are designed to begin the process of coagulation or clot formation whenever a tissue or blood vessel is broken.<br />
  11. 11. Blood Vessels<br /> The blood vessels are the vast networks of small tubes that carry blood throughout the body . It is like a water pipe that carries water to the different places.<br />If you could take all the blood vessels out and line up end to end, they would measure about 96 600 kilometers. There are 3 types of blood vessels in your body . These are arteries, veins and capillaries. The network of blood vessels spreads through the entire body, even into the bones and muscles.<br />
  12. 12. Types of Blood Vessels<br />ArteryThese blood vessels carry oxygenated blood away from the heart. The largest artery is the aorta. While the smallest is the arterioles.<br />VeinsThese blood vessels carry deoxygenated blood back to the heart. The largest vein is the vena cava. While the smallest is the venules.<br />CapillariesThese blood vessels connect the veins and the arteries.<br />
  13. 13. Path Of Circulation<br />
  14. 14. Types of Circulation<br />Pulmonary Circulation:<br />Vena Cava -Right Atrium-Tricuspid Valve-Right Ventricle-Pulmonary Artery-LUNGS<br />Systemic Circulation:<br />LUNGS-Pulmonary Vein-Left Atrium-Bicuspid Valve-Left Ventricle-AORTA<br />
  15. 15. Ailments of The Circulatory System<br />Heart Diseases<br />Congenital Heart Disease<br />Angina Pectoris<br />Heart Failure<br />Blood Vessel Diseases<br />Aneurysm<br />Hypertension<br />Arteriosclerosis<br />Stroke<br />Thrombosis<br />Blood Diseases<br />Anemia<br /><ul><li>Iron-deficiency anemia
  16. 16. Aplastic anemia
  17. 17. Sickle-cell anemia</li></ul>Polycythemia<br />Leukemia<br />Hemophilla<br />Purpura and Petichiae<br />
  18. 18. Ways to Keep Your Circulatory System Healthy<br /><ul><li>Exercise Regularly
  19. 19. Eat a well-balanced and low fat diet
  20. 20. Live in a clean environment
  21. 21. Avoid smoking or staying with smokers
