1. The process of giving birth to a baby. After a pregnant woman is 9 months pregnant, the fetus is fully developed and ready to be born. After a pregnant woman enters the delivery room, the doctor will check the fetal position and cervical opening, and then provide appropriate analgesic measures. Next, the pregnant woman begins to exert force to push the fetus out of the body smoothly. During this process, doctors will assist pregnant women with operations such as dilation of the birth canal and adjustment of fetal position. 2. Different ways of delivery There are many ways of giving birth, including vaginal delivery, caesarean section, in vitro fertilization, etc. Among them, vaginal delivery is the most natural way of delivery, which can reduce complications and surgical risks during pregnancy; caesarean section is suitable for pregnant women or fetuses who are pregnant.
