Cardiovascular Physiology Exam Questions with correct answers provided

Cardiovascular Physiology Exam Questions with correct answers provided Explain why the larger waves seen on the oscilloscope represent ventricular contraction -the ventricle contraction is of greater force than the atrial contraction, this is due to the fact that ventricles function is to send blood throughout the body explain why the amplitude of the wave did not change when you increased the frequency of the simulation -amplitude does not change because the cardiacs long refractory period prevents summation why is it only possible to induce an extrasystole during relaxation -the extrasystole cannot occur until relaxation so we cannot achieve wave summation tetanus explain why wave summation and tetanus are not possible in cardiac muscle tissue. - cardiac cells have longer A Ps and twitches than any other muscle cells, therefore they do not show temporal summation
