Why do blood will acccumulate in legs if we

  1. Aug 31, 2006 #1
    Good evening everyone,

    I wonder why our blood will accumulate in legs if we don't walk or jog after a running competition. [HKALE2006]

    Is it because if we don't walk or jog , the skeletal muscle will not keep contracting and the venous blood will not return to the heard via Vena Cavae in a faster rate, so the blood that supplied skeletal musles during competition > the blood that can return to our heart, and thus, accumulate in legs??
    I don't know if I am correct or is there any ways to think biologically?
    Please teach me a bit. Thanks!!!!
