    Contractility, MAP, and Kinetic energy of blood

    Hi everyone, It would seem to me that blood pressure would be due to the amount of blood in a vessel as well as the force that blood was ejected from the left ventricle with since blood ejected with a greater force could exert a greater force on the wall of an artery. However, the equation for...

    Fellow SDNers, I wanted to ask a question on the action potential(AP), Ca+2 transient and cardiac muscle twitch is affected when we either experimentally introduce more extracellular Ca+2 or administer isoproterenol. From what I understand when you would increase the extracellular Ca+2 more...
