This Medical Video: Childbirth (also called labour, birth, partus or parturition) is the
culmination of a human pregnancy or gestation period with birth of
one or more newborn infants from a woman’s uterus. The process of
normal human childbirth is categorized in three stages of labour
the shortening and dilation of the cervix, descent and birth of the
infant, and birth of the placenta. In some cases, childbirth is
achieved through caesarean section, the removal of the neonate
through a surgical incision in the abdomen, rather than through
vaginal birth
