Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	Blood returns to the atria
B	A decrease in atrial pressure pushes open the AV valves
C	SL valves are open
D	Blood enters the ventricles

Explanation:

Detailed explanation-1: -Diastole begins with the closing of the aortic valve (or pulmonic) and ends with the closing of the mitral valve (or tricuspid). This period encompasses the ventricular relaxation and filling. Diastole represents when the blood vessels return blood to the heart in preparation for the next ventricular contraction.

Detailed explanation-2: -Ventricular diastole, diastole, ventricular systole, atrial systole.

Detailed explanation-3: -1.1. The cardiac cycle includes two phases: diastole and systole (Fig. 1.4). In the diastole phase, blood returns to the heart from the superior and interior vena cava and flows into the right atrium. The pressure in the right atrium increases as blood flows into it.
