gcse biology help!
Can someone please confirm whether this is correct and in the right order: (i find it so confusing)
The menstrual cycle:
FSH (pituitary) - matures egg, stimulates oestrogen
Oestrogen (ovaries) - builds up uterus lining, inhibits FSH and stimulates LH
LH (pituitary) - releases egg - day 14, inhibits oestrogen and stimulates progesterone
Progesterone (ovaries) - maintains the lining of the uterus, inhibits LH
The menstrual cycle:
FSH (pituitary) - matures egg, stimulates oestrogen
Oestrogen (ovaries) - builds up uterus lining, inhibits FSH and stimulates LH
LH (pituitary) - releases egg - day 14, inhibits oestrogen and stimulates progesterone
Progesterone (ovaries) - maintains the lining of the uterus, inhibits LH
