Oct 3, 2022 · The cardiac cycle is a series of pressure changes within the heart. These pressure changes result in blood movement through different chambers of the heart and the body as a whole.
19.3 Cardiac Cycle – Anatomy & Physiology
The cardiac cycle comprises a complete relaxation and contraction of both the atria and ventricles, and lasts approximately 0.8 seconds. Beginning with all chambers in diastole, blood flows passively from the veins into the atria and past the atrioventricular valves into the ventricles.
The Cardiac Cycle | Wigger’s diagram | Geeky Medics
May 7, 2022 · The cardiac cycle can be divided into systolic (contraction) and diastolic (relaxation) phases. The cycle goes in the following order: atrial systole, ventricular systole and diastole.
