Body Fluids and Circulation

Which one of the following statements is correct?

  1. A.Increased ventricular pressure causes closing of the semilunar valves
  2. B.The atrio-ventricular node (AVN) generates an action potential to stimulate atrial contraction
  3. C.The tricuspid and the bicuspid valves open due to the pressure exerted by the simultaneous contraction of the atria
  4. D.Blood moves freely from atrium to ventricle during joint diastole✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
