Question

Quizplus · Accepted Answer

Oxytocin is the hormone that causes strong contractions of the uterus during labor. It is released by the pituitary gland in response to the baby's head pressing against the cervix, and it helps to push the baby out of the uterus during delivery. Other hormones like estrogen and progesterone also play important roles in pregnancy, but they do not directly stimulate uterine contractions during labor. HCG (human chorionic gonadotropin) is a hormone produced by the placenta during early pregnancy, and it helps to maintain the pregnancy by stimulating the production of other hormones like estrogen and progesterone.
