The most drastic change in the uterus is the contraction from an organ weighing one kilogram and a volume of about 10 litres down to a 60 gram organ that only contains 5 ml of fluid. [7] Immediately after delivery, the fundus of the uterus begins to contract.
As the fetal hypothalamus matures, the activation of the hypothalamic–pituitary–adrenal (HPA) axis initiates labor through two hormonal mechanisms. The end pathway of both mechanisms lead to contractions in the myometrium, a mechanical cause of placental separation, which is due to the sheer force and contractile and involutive changes that occur within the uterus, distorting the placentome.
Placental abruption is when the placenta separates early from the uterus, in other words separates before childbirth. [2] It occurs most commonly around 25 weeks of pregnancy . [ 2 ] Symptoms may include vaginal bleeding , lower abdominal pain , and dangerously low blood pressure . [ 1 ]
