Final answer:
The process of expelling an infant from the uterus is known as parturition, consisting of three stages including cervical dilation, expulsion of the newborn, and the passage of the placenta.
Step-by-step explanation:
The series of events that expel the infant from the uterus are referred to collectively as parturition. Therefore, the correct answer is B) Parturition. This process can be divided into three stages: cervical dilation, the expulsion of the newborn, and the afterbirth (the passage of the placenta). During the first stage of parturition, the cervix thins and dilates to allow the baby to pass through the birth canal. In the second stage, the baby is expelled from the uterus, and during the last stage, the placenta is passed after the baby has been born.
