The uterus is a muscle. During menses it contracts to expel the uterine lining and menstrual blood. This is a mild from of the contraction it does to push out a baby. The contraction can press against a blood vessel and cut off the blood supply. This pinching off of the blood supply causes the cramping.Answer 2:I believe it's because of the shedding of the uterus lining.
Oxytocin.
Oxytocin is a hormone released by the pituitary gland. It causes increased contraction of the uterus during labor. Next time, actually do your bio homework though (;

Uterine contractions occur when a pregnant woman goes into labor. The purpose is to dilate the cervix and to push the baby into the vagina, out of the uterus, during birth. The uterus continues to contract after expelling the baby and placenta to clamp down on any bleeding (prevent hemorrhage) and shrink the uterus.
This is the result of your uterus stretching to accommadate your babies arrival Its the way the uterus resizes itself before and after the baby comes
Oxitosin is the hormone. It is secreted by pituitary.
Asystole means without contraction of the heart. Atony is a term used to denote no normal muscle contraction of the uterus.
Oxytocin is made in the posterior pituitary. Oxytocin prompts the let-down reflex, and stimulates contraction of the uterus during childbirth.
uterus is the organ and reproductive/endocrine system cause the contraction (hormone-oxytocin is released in the body that causes the contractions to occur. If a woman is induced for labor pitocin is given which is the "man made" form of oxytocin
Because during your period your uterus contracts which causes the cramping pain to expel the uterine lining. During labor the uterus does the same action to help deliver a baby.
