Question

briefly describe the three events in cardiac cycle in humans

Answer 1

Dear student,

The cardiac cycle is the sequence of events that occurs when the heart beats. As the heart beats, it circulates blood through pulmonary and systemic circuits of the body.
There are two phases of the cardiac cycle: 1.Diastole phase 2.Systole phase
In the diastole phase, the heart ventricles are relaxed and the heart fills with blood. In the systole phase, the ventricles contract and pump blood to the arteries.
