Final answer:
The stage of labor that begins with the complete dilation of the cervix and ends with the delivery of the fetus is called stage two or the expulsion stage of labor.
Step-by-step explanation:
The stage of labor that begins with the complete dilation of the cervix and ends with the delivery of the fetus is called stage two or the expulsion stage of labor.
During this stage, the baby is expelled from the uterus through the birth canal. The uterus contracts, and the person giving birth pushes to aid in the delivery. This stage typically lasts for a few minutes to a couple of hours.
After the baby is born, the third stage of labor occurs, which involves the delivery of the placenta and associated fetal membranes.
In stage two of labor, the culmination of uterine contractions and maternal pushing facilitates the baby's journey through the birth canal. This stage, lasting minutes to hours, concludes with the joyous moment of delivery. Subsequently, stage three unfolds, involving the expulsion of the placenta and fetal membranes, marking the comprehensive conclusion of the labor process. This multifaceted sequence underscores the dynamic nature of childbirth and the intricate physiological processes that ensure a safe and successful delivery for both mother and baby.
