Final answer:
The word that means after birth or labor is 'postpartum,' which refers to the period immediately following childbirth when the mother's body returns to a non-pregnant state.
Step-by-step explanation:
Antepartum is a term used to describe the period before birth or labor. To answer the question, the word that means after birth or labor is postpartum. This term is associated with the period immediately following childbirth, a time during which the body of the mother gradually returns to its non-pregnant state. This postpartum period includes the delivery of the placenta and is often considered to be approximately 6 weeks in duration. The delivery of the placenta itself is known as the afterbirth, marking the final stage of childbirth, which is a three-stage process involving dilation of the cervix, birth of the baby, and the delivery of the placenta.
