Summary of Stages of labor
Labor is the process by which the fetus and placenta leave a woman’s uterus, thereby ending the pregnancy. It occurs roughly 40 weeks after the beginning of the last menstrual period. Vaginal delivery involves three stages of labor: the shortening and opening of the cervix, descent and birth of the baby, and the delivery of the placenta.
