What is the function of oxytocin?

Explanation:
Oxytocin’s main function is to stimulate uterine contractions during childbirth. It is produced in the hypothalamus and released from the posterior pituitary in response to labor signals. When oxytocin binds to receptors on uterine smooth muscle, it raises intracellular calcium and drives rhythmic contractions that help progress labor and deliver the baby. After birth, it also facilitates milk ejection from the lactating breast when the infant suckles. The other options don’t fit because oxytocin isn’t the hormone that regulates blood sugar, lowers blood pressure, or controls metabolism; those roles belong to other hormones.
