Answer:

(a) Diagram: human female reproductive system (front view)

        fallopian tube (oviduct)          fallopian tube (oviduct)
   fimbriae  __________                  __________  fimbriae
   (funnel) /          \________________/          \ (funnel)
      ( O )                |          |                ( O )
      ovary                |  uterus  |                ovary
                           |   (with  |
                           | endometrium)
                            \        /
                             | cervix|

                             | vagina|
                             |_______|
                           vaginal opening

Labels: ovaries, fallopian tubes (oviducts) with funnel-shaped fimbriated ends, uterus, endometrium (inner lining of uterus), cervix, vagina.

(b) The ovaries secrete the female sex hormones oestrogen and progesterone.

(c) Menopause occurs at about 45–50 years of age. At menopause the menstrual cycle stops permanently, the release of ova stops and the secretion of ovarian hormones (oestrogen and progesterone) declines greatly.

(d) A female foetus has two ovaries at birth; they contain 2 to 4 million (20 to 40 lakh) immature eggs (oocytes).
