Hi firstly this is my first post here so if I am writing this in the wrong place please put it in the right place. I am currently taking Core Science and know the specifications and everything however I am confused on a certain topic of hormones.I know what hormones are they are chemical messengers which travel in blood to activate target cells, I know FSH and LH are produced by the pituitary glands and oestrogen and progesterone by the ovaries as well as the menstrual cycle. For this exam (Science A core science) do we need to what LH and FSH stand for and do we need to link the the hormones to the menstrual cycle me and my friend came up with conclusion.
Day 1-4 high levels of FSH which make the lining thin
Day 4-14 FSH helps produce oestrogen which makes the lining thicker and helps produce LH which releases the egg.
Day 14-28 LH helps produce progesterone which maintains the lining then the cycle is repeated.
Thanks for reading if i am wrong can you explain this to me, if i am right tell me and i think ill be able to smash the rest of the exam thanks in advance
