1. A non-pregnant female's uterus shed its lining (the outer endometrial layer) every 4 weeks and then begins the menstrual cycle anew, the cycle's timing being controlled by female reproductive hormones. A successful pregnancy requires that the menstrual cycle be interrupted and the fetus left undisturbed for 9 months. Cycle interruption is accomplished by the fetal placenta, which secretes several key hormones that manipulates maternal reproductive physiology. Give at least three (3) hormones that control the maternal reproductive physiology, give their specific functions/role.
