Vedclass · Answer

(A) Diagram $A$: The atria are filling with blood from the venae cavae and pulmonary veins,while the atrioventricular valves are closed. This indicates that the atria are in a relaxed state,known as atrial diastole.Diagram $B$: The atria are contracted,and the bicuspid and tricuspid valves are open,allowing blood to flow into the ventricles. This state is called atrial systole.Diagram $C$: The semilunar valves are open,and blood is being pumped into the pulmonary artery and aorta. This occurs due to the contraction of the ventricles,a state known as ventricular systole.
