Parturition is the process of giving birth, marking the end of pregnancy. It involves a series of physiological changes that help the body prepare for labor and delivery. The process typically begins with contractions of the uterus, which help to push the baby through the birth canal. During parturition, several stages occur, including dilation of the cervix and the actual delivery of the baby. After the baby is born, the placenta, which nourished the baby during pregnancy, is also expelled. This process is crucial for the health of both the mother and the newborn, ensuring a safe transition into the world.
