Which one of the following statements is correct?

The tricuspid and the bicuspid valves open due to the pressure exerted by the simultaneous contraction of the atria

Blood moves freely from atrium to the ventricle during joint diastole

Increased ventricular pressure causes closing of the semilunar valves

The atrio-ventricular node (AVN) generates an action potential to stimulate atrial contraction

Given below are two statements: Statement I: The coagulam is formed of network of threads called thrombins. Statement II: Spleen is the graveyard of erythrocytes. In the light of the above statements, choose the most appropriate answer from the options given below:

Statement I is incorrect but statement II is correct

Both statement I and statement II are incorrect

Statement I is correct but statement II is incorrect

Both statement I and statement II are correct
