Question

the phase of cardiac cycle in which the auricles contract

Answer 1

It consists of three phases namely: 1. Atrial systole – The atria (and auricles)contract. The tricuspid and bicuspid valves open and blood fills the ventricles as the atria empty

Answer 2

the diastole phase, the heart ventricles are relaxed and the heart fills with blood. In the systole phase, the ventricles contract and pump blood out of the heart and to arteries. One cardiac cycle is completed when the heart chambers fill with blood and blood is then pumped out of the heart.
