Detailed explanation-1: -During natural labor, uterine contractions increase in intensity and force the fetus into the birth canal. Stretch of the cervix causes the reflex release of additional oxytocin from the posterior pituitary, further increasing the strength of uterine contractions in a positive feedback cycle.
Detailed explanation-2: -What is labor? Labor is a series of continuous, progressive contractions of the uterus which help the cervix to open (dilate) and to thin (efface), allowing the fetus to move through the birth canal.
Detailed explanation-3: -Strong uterine contractions compress uterine blood vessels, preventing a continuous hemorrhage at childbirth.
Detailed explanation-4: -During childbirth, the muscles at the top of your uterus contract and push your baby towards your cervix. If your baby is facing head-down, the head will press on your cervix. This, along with the release of the hormone oxytocin (see ‘How hormones help you give birth’, below), brings on contractions.
