What is the term for the removal of the placenta after childbirth?

The term for the removal of the placenta after childbirth is referred to as the "afterbirth." This term specifically describes the placenta and membranes that are expelled from the uterus after the baby is born.

During the process of childbirth, once the baby is delivered, the body goes through a series of contractions which help to detach the placenta from the uterine wall. The expulsion of these remains, which is an important next step in the delivery process, is what is termed "afterbirth."

Other options do not specifically denote the expulsion of the placenta. "Delivery" generally refers to the act of giving birth to the baby itself. "Placental expulsion" is a descriptive phrase, but it is not the commonly used term in medical contexts. "Childbirth" encompasses the entire process of bringing the baby into the world, including labor and delivery, but does not specifically refer to the placenta. Therefore, "afterbirth" is the correct term that accurately describes the event of the placenta being expelled after the birth of the child.
