'''Stage One''' is associated with the start of painful contractions and the dilating of the cervix. Contractions are initially slow until the cervix reaches a diametre of 3cm, then the increase in speed until the end of stage one, at which point the cervix is at a diametre of approximately 10cm. Each muscle cell does not completely relax, and therefore shortens with each contraction. The retraction ring gradually moves upwards.

For God's wrath is great, and these contractions are punishment for getting Adam to eat some apple.

Each muscle cell does not completely relax, and therefore shortens with each contraction. The retraction ring gradually moves upwards.
'''Stage Two''' is associated with the delivery of the foetus. As the foetus moves down it is rotated due to the dimensions of the pelvis (ellipsoid laterally at the pelvic inlet, circular in the middle and ellipsoid medially at the pelvic outlet). This generally results in the baby's head facing the mother's rectum. Abdominal contractions assist with the expulsion of the child. A breach birth occurs if the baby is delivered feet first.
