Question 2

Female period cycle

Answer 2

1) FSH - from pituitary - stimulates folicle to mature and produce estrogen
2) Estrogen - from ovary - thickens uterine wall and stops FSH
3) LH - from pituitary - ruptures follicle, repairs it (into corpus luteum)
4) Progesterone - from pituitary - keeps uterine wall thick and keeps FSH off

Question 3

Why is it important for the hormone made by the membranes around the embryo to keep the corpus luteum alive?

Answer 3

IF THE CORPUS LUTEUM IS ALIVE IT KEEPS MAKING PROGESTERONE WHICH KEEPS WALL OF UTERUS THICK – SO DEVELOPING BABY CAN STAY ATTACHED AND THE PLACENTA CAN FORM – FROM WHICH DEVELOPING BABY GETS ITS NOURISHMENT AND GETS RID OF ITS WASTE. IF CORPUS LUTEUM SHRIVELS UP THEN NO PROGESTERONE AND EXTRA LINING OF UTERUS LEAVES – MENSTRUATION – NEW CYCLE.
