List the steps of the cardiac cycle

The 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.) Moving from the left along the Wiggers diagram shows the activities within four stages during a single cardiac cycle. (See the consecutive panels labeled, at bottom-right, "Diastole" then "Systole").
