The flashcards below were created by user kmhs320 on FreezingBlue Flashcards. What would you like to do?


  1. Chamber of the heart:
    Two Atria (Singular: atrium), which receives blood

    Two Ventricles, which pump blood to the body
  2. Where does blood enter the heart?
    Right atrium from the upper and lower body through veins called the superior vena cava and the inferior vena cava.
  3. What is the purpose of a valve?
    To prevent backflow when the ventricles contract.
  4. After blood enters the right atrium from the superior vena cava and inferior vena cava it then pass thru ___________ valve into the ________ __________.
    atrioventricular valve into the right ventricle.
  5. After blood enters the right atrium from the superior vena cava and inferior vena cava then pass into the right ventricle. The right ventricle then pumps blood thru the                    valve into the                                   .
    semilunar valve into the pulmonary arteries.
  6. What is the purpose of the pulmonary arteries?
    To carry the blood to the lungs so that it can become oxygenated.
  7. After blood enters the right atrium from the superior vena cava and inferior vena cava then pass into the right ventricle. The right ventricle then pumps blood into the lung thru the pulmonary arteries. Blood then leaves the lungs via _______ ________.
    pulmonary veins, which returns newly oxygenated blood to the left atrium.
  8. After newly oxygenated blood enters the left atrium, via the pulmonary veins, it then passes through another _________ valve to the ________ _______.
    atriovetricular valve to the left ventricle.
  9. After newly oxygenated blood enters the left atrium, via the pulmonary veins, and then into the left ventricle...what happens to get blood pumped through the body.
    Muscular contractions of the left ventricle pump blood through the aorta to all parts of the body.
  10. Systole

    Diastole Pressure?
    Systole...contraction of the heart..pressure increases

    Diastole...relaxation of the heart...pressure decrease
  11. What is coronary circulation? 

    What is pulmonary circulation?

    What is systemic circulation?
    The circulation of blood to the heart.

    The circulation of blood through the lungs. 

    The circulation throughout the body.
  12. What type of tissue is blood consider?
    Connective Tissue
  13. Red blood cells, white blood cells and platelets make up ____% of whole blood?

    Whereas plasma (which contains proteins, ions, hormones, and gases) makes up the other ____%
    45%

    55%
  14. There are approx. ____ molecules of hemoglobin in each RBC.
    250 million
  15. What is hemoglobin?
    Iron-rich compound, that is an oxygen carrier. This explains the need for iron in our diets.
  16. What are platelets?
    Also found in plasma, which are pieces of cells that are important in blood clotting.
  17. What are the 3 kinds of blood vessels?
    Arteries

    Veins

    Capillaries
  18. What are arteries? What is unique about them, in terms of their features?
    Carries blood away from the heart. Unique because arteries are muscular since they have to carry blood at relatively high pressure.
  19. What are veins? And what is unique about them?
    Carries blood TO the heart.  Unique because veins contain valves to prevent the blackflow of blood as it returns to the heart.
  20. What are capillaries? And what is unique about them?
    Tiny blood vessels that connect arteries and veins. Unique because Through the capillary walls (only one cell thick), materials can enter and leave the blood.
