During the systole of ventricle

Assertion : During diastole, ventricles receives blood from auricles. Reason : During ventricular diastole (stage of rapid inflow) the pressure inside auricles is greater than ventricles.

Differentiate between atrial systole and ventricular systole.

How can you explain the following ? (i) Auricles have thinner walls than ventricles. (ii) Blood flows under pressure in the arteries. (iii) Heart has striped muscles unlike other viscera. (iv) There is a slight gap between auricular systole and ventricular systole.

Atrial systole
