  8. 8

    The most important single factor in determining vascular resistance is:

  9. 9

    Two way exchange of substances between blood and body tissue cells occurs mostly through:

  10. 10

    The cardiac output cannot increase indefinately because:

  11. 11

    Blood flow in the capillaries is slow & intermittent because:

  12. 12

    The structure of a capillary wall differs from that of a vein or an artery because:

  13. 13

    The amount of blood forced (stroke volume) out of the heart during systole depends on:

  14. 14

    Blood is normally transported through the venous system and back to the heart by means of:

  15. 15

  21. 21

    The portion of the intrinsic cardiac nodal conduction system flowing through the interventricular spetum is/are the:

  22. 22

    The layer of the arteriole that provides the properties of contractility and elasticity is the:

  23. 23
