Question

Name the following: The phase of cardiac cycle in which the auricles contract.

Answer 1

The cardiac cycle describes the biological events which take place in the heart for the span of a heartbeat. 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.

2.       Ventricular systole – The ventricles contract, the tricuspid and bicuspid valves close and the semilunar valves open, allowing blood to flow through the aorta and pulmonary artery.

3.       General Diastole – atria and ventricles relax, the semilunar valves close, and blood fills the left and right atria from the pulmonary vein and superior and inferior vena cava, respectively.
