    I've got a question regarding the cariac cycle:

    When do you describe the SAN...

    and when do you describe Systole...
    Well .. in my exam last week they asked me to describe the cardiac cycle including these words :
    -SAN
    -AVN
    -Puryne tissue

    These tissue are involved in the intiation/ transmission of Heart beat.
    so obviously i should talk about the journey of the WAVE OF EXCITATION intiated by the SAN, through the heart walls.
    However if they have included arteries, ventricles,viens and atrium .. then i should of talked about the journey of BLOOD through the heart.

    i suppose the Term cardiac cycle = for the movement of Blood through the heart.So if they asked u to descride the stages of cardiac cycle then i think u should talk about movement of blood through heart.And if they asked about how the heart beat intiated .. then talk about SAN,AVN,&purkyne tissue.

    The sinoatrial node is the term used to describe the modified cardiac muscle in the right atrium responsible for initiating the simultaneous contraction of the atria, termed atrial systole.
