The heart

  1. 1. The Human Heart
  2. 2. Parts of the Internal Heart 1 2 3 4 5 6 7 8 9 10 11 Path of Blood Flow
  3. 3. Pulmonary Valve <ul><li>Keeps blood from flowing back into the right ventricle </li></ul>Back to the Heart
  4. 4. Bicuspid Valve <ul><li>Prevents blood from flowing back into the left atrium </li></ul><ul><li>Also called the Mitral valve </li></ul>Back to the Heart
  5. 5. Left Atrium <ul><li>Receives oxygen rich blood from the pulmonary veins </li></ul>Back to the Heart
  6. 6. Pulmonary Trunk <ul><li>Transfers blood through the pulmonary arteries to the lungs </li></ul>Back to the Heart
  7. 7. Aortic Valve <ul><li>Prevents blood from going back into the left ventricle </li></ul>
  8. 8. Tricuspid Valve <ul><li>Prevents backflow of blood to the right atrium </li></ul><ul><li>3 cusps </li></ul>Back to the Heart
  9. 9. Aorta <ul><li>Blood flows from the aorta throughout the entire body </li></ul><ul><li>Largest vessel in the body </li></ul>Back to the Heart
  10. 10. Left Ventricle <ul><li>Pumping chamber which forces blood through the aortic valve </li></ul><ul><li>More muscular than the right ventricle </li></ul>Back to the Heart
  11. 11. Right Atrium <ul><li>Collecting chamber </li></ul><ul><li>Blood is forced to the right ventricle </li></ul>Back to the Heart
  12. 12. Interventricular Septum <ul><li>Separates the pumping chambers of the heart </li></ul>Back to the Heart
  13. 13. Superior Vena Cava <ul><li>Blood from the SVC & IVC is released into the right atrium </li></ul>Back to the Heart
  14. 14. Path of Blood Flow <ul><li>Place the following items in the correct sequence: body tissue, aorta, bicuspid valve, left atrium, lungs, pulmonary trunk, pulmonary arteries, left ventricle, pulmonary veins, right atrium, right ventricle, tricuspid valve, aortic valve, pulmonary valve. </li></ul><ul><li>Oxygen poor blood is collected from the inferior and ___________ _______ ________. It is released into the _________ _______ where it moves through the _________ valve into the ________ __________. When the right ventricle contracts, blood is forced through the _________ valve into the ____________ _______ which splits into the left & right pulmonary __________. Blood is taken via the arteries to the _____ where oxygen & carbon dioxide diffuse through the simple squamous tissue. Oxygen-rich blood then returns to the heart via the ___________ ________ which empty into the _________ ________. Once the atrium contracts, the blood passes through the __________ ________ into the _________ _________. Once the ventricle contracts blood is forced through the _________ valve and out of the _________ to travel to the _______ ________ . </li></ul>Answer
  15. 15. Right Ventricle <ul><li>Receives blood from the superior and inferior vena cava </li></ul>Back to the Heart
