Answer 2

Answer:

1.Fallopian tube

2.Ovary

3.Cervix

4.Uterus

5.Vagina

(a) Ovary- production of egg

(b) Fallopian tube- fertilisation

(c) Uterus - Implantation of zygote

Before the release of egg the uterus prepares itself to receive an egg every month, and hence forms a thick lining of blood and mucus.

If no fertilisation occurs, the thick lining tears off and comes out of vagina in the form of blood and mucus. this is called Menstruation.
