Write short note on female reproductive system.

Explanation

Female reproductive system consists of a pair of ovary, a pair of oviduct (fallopian tubes), an uterus, a vagina and vaginal opening.

Ovary : One pair of ovary lie inside the abdominal cavity of a woman. The female germ cells or eggs (ova) are formed in the ovaries. Ovary produces female sex hormones such as estrogen and progesterone.
When a girl is born, the ovaries already contain thousands of immature eggs. On reaching puberty, some of these egg cells start maturing. One egg is produced every month by one of the ovaries.
Oviduct (Fallopian tube) : One pair of oviducts are present which are not attached to ovaries.
The egg is carried from the ovary to the uterus (womb) through a thin oviduct.
The fertilisation of egg cell by a sperm takes place in the initial part of the oviduct.
Uterus : The two oviducts unite into an elastic bag-like structure called uterus.
The implantation and development of embryo occurs here. The distal narrow end of uterus is called cervix.
Vagina : Through the cervix, uterus opens in to tubular structure vagina. Vagina opens outside through the vaginal opening.
The sperms enter through the vaginal passage during sexual intercourse.
