CBSE Class 10 Science 2022 · Paper 31(B)/5 · Question 10(b)
Write the functions of the following parts of the human female reproductive system :
- (i)Ovary
- (ii)Fallopian tube
- (iii)Uterus
Answer
The ovary makes eggs, the fallopian tube carries the egg and is the site of fertilisation, and the foetus develops in the uterus.
(i) Ovary: produces the female gametes, the eggs (ova); from puberty one egg is produced every month by one of the ovaries. The ovaries also secrete the female sex hormones, such as oestrogen.
(ii) Fallopian tube (oviduct): carries the egg from the ovary towards the uterus, and is the site of fertilisation, where a sperm fuses with the egg.
(iii) Uterus: the fertilised egg (zygote) is implanted in its thick, blood-rich lining and develops there into the embryo and foetus, which is nourished from the mother's blood through the placenta; at birth, rhythmic contractions of its muscles push the baby out.
