WebThe cardiac cycle is a continuous sequence of events that occur in the heart, including both contraction (systole) and relaxation (diastole) of the atria and ventricles. The cycle can be divided into several phases as described below: During this phase, both atria and ventricles are in a relaxed state (diastole). WebThe 5th Phase: Late Ventricular Diastole. What happens during Atrial Systole? - P-wave: depolarization of atrial muscle, atria contracts - Pressure in atria is greater than pressure in ventricles - ventricles are still filling ...

"WebThe filling pattern is divided into three phases: a dominant systolic phase, a diastolic phase, and a third short atrial contraction phase with small reversal (upstream) flow from the RA into the systemic veins. During diastole the tricuspid valve opens, and blood from the RA is drained into the RV in two phases, early and late diastolic filling. " - Diastole and systole phases

WebThe cardiac cycle is a repeating process by which the heart pumps blood into circulation. It consists of two phases: the diastole (relaxation) phase and the systole (contraction) phase. During diastole, major events … WebFeb 2, 2024 · Ans: The cardiac cycle is divided into two phases: diastole and systole. They happen as the heart beats, moving blood through a system of blood vessels that transports blood to all parts of the body. When the heart contracts to pump blood out, it is called systole, and when it relaxes after contraction, it is called diastole. ...
