Key Concepts

Cardiac Cycle

The cardiac cycle is the sequence of events that occur during one complete heartbeat, including phases of contraction (systole) and relaxation (diastole). Ventricular systole, where the ventricles contract, is especially important in this cycle because it is the main force driving the blood away from the heart into the arteries.

Cardiac Ventricular Contraction

This concept refers to the process by which the ventricles of the heart contract forcefully to push blood out of the heart into the circulatory system. It is a critical mechanism that generates the high pressure needed to overcome peripheral resistance and ensure that blood is efficiently circulated throughout the body.
