| Second - the rupture event looks so violent but iiuc it's

| in the ovulation process - the expansion step pulls in fluid to
| the ovary (builds internal pressure) - the contraction phase
| restricts the cell volume (which also builds internal pressure) -
| the oocyte is launched out of the cell at a relatively high speed
