Human Development and Pregnancy
Parturition, or childbirth, is the delivery of an infant following gestation.
Stages of Labor
Vaginal delivery childbirth has three distinct phases: dilation of the cervix, delivery of the infant, and delivery of the placenta.
Adjustments of the Infant at Birth
Post birth, an infant's physiology must adapt to breathing independently, changes in blood flow and energy access, and a cold environment.
