WebMar 22, 2024 · A normal heart has valves, arteries and chambers that carry the blood in a circulatory pattern: body–heart–lungs–heart–body. When all chambers and valves work correctly, the blood is pumped through the heart, to the lungs for oxygen, back the heart and out to the body for delivery of oxygen. WebThe cardiac cycle involves four major stages of activity: 1) "Isovolumic relaxation", 2) Inflow, 3) "Isovolumic contraction", 4) "Ejection". (See Wiggers diagram, which presents the stages, label-wise, in 3,4,1,2 order, left-to-right.)
