網頁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. Heart valves open when the pressure of the chamber lying before it is higher than that of the chamber after the valve. 網頁As blood returns from the lungs it flows into the left atria, through the AV valve, into the ventricle The ventricular cells depolarize and begin to contract The atria cells depolarize and contract to squeeze the last bit of blood out to the all info is there Show transcribed image text Expert Answer 100% (1 rating) 1st step All steps Final answer

"網頁2024年10月19日 · There are five cardiac action potential phases, numbered 0 through 4 (scientists get strange ideas sometimes). Phase 0 is depolarization of the membrane and the opening of "fast" (i.e., high-flow) sodium channels. Potassium flow also decreases. Phase 1 is partial repolarization of the membrane thanks to a rapid decrease in sodium-ion … " - Steps of cardiac cycle in order
