The tissue and membranes that are released from a mother's body after giving birth.
The doctor examined the afterbirth to ensure that everything was expelled properly.
Afterbirth → It is formed from "after" (from Old English "æfter", meaning following in time or place) and "birth" (from Old English "berthan", meaning to bring forth or give birth). The word "afterbirth" refers to the placenta and other membranes expelled after the birth of a baby.
Think of something that comes 'after' ('after') the act of 'giving birth' ('birth') — that's what afterbirth means.
