Lesson 5

  1. List five major functions of the cardiovascular system.
    • 1) transport oxygen
    • 2) remove carbon dioxide
    • 3) transport chemical mediators
    • 4) thermoregulation
    • 5) transport leukocytes
  2. Name the structural components of the human heart
    Major structures of the heart are the superior and inferior vena cava, the left and right atriums, left and right ventricles, and pulmonary arteries, veins, and capillaries, and the aorta.
  3. the flow of blood through the various chambers, valves, and major blood vessels attached to the heart
    The superior and inferior vena cava carry oxygen poor blood from veins to the right atrium, the right atrium moves blood through the tricuspid valve to the right ventricle. Then the right ventricle contracts and pumps blood through the pulmonary semilunar valve and into the pulmonary trunk. The pulmonary trunk moves oxygen poor blood into the pulmonary arteries which go into the lungs. Pulmnonary capillaries located in the lungs conduct a gas exchange, allowing oxygen to enter the blood while carbon dioxide leaves it. Pulmonary veins take the now oxygen rich blood to the left atrium. The left atrium pumps blood to the bicuspid valve to the left ventricle. The left ventricle sens blood into the aorta.
  4. name the system that recovers fluid that escapes from the capillaries
  5. Lymphatic System.
  6. What are the major components of the lymphatic system?
    1) lymph vessel; 2) lymph nodes; 3) white blood cells; 4) bone marrow; 5) lymph organs including tonsils, spleen, and thymus.
  7. helps relieve high blood pressure
    diuretic
  8. relieved by nitroglycerine
    angina
  9. plaque accumulation
    atherosclerosis
  10. blown blood vessel
    aneurysm
  11. can lead to edema
    congestive heart failure
  12. What is the lub sound of the heart?
    The first heart sound.
  13. True or False?

    All arteries carry blood away from the heart
    True
  14. The QRS complex represents
    systole of the ventricles
