(a) Write the functions of each of the following parts in a human female reproductive system:
(i) Ovary (ii) Uterus (iii) Fallopain tube
(b) Write the structure and functions of placenta in a human female.

Explanation

(a) (i) Ovary. It produces the egg cell and also produces the female hormones-estrogen and progestrone.
(ii) Uterus. Implantation of zygote takes place in the uterus. Here the embryo develops into foetus and then foetus develops into the baby to be born.
(iii) Fallopian tube. This is the site of fertilization of the egg with sperm (male gamet). It also helps in the transfer of female gamete from the ovary.
(b) Structure of placenta. It is a disc like special tissue which is embedded in the uterine wall. It has finger like villi on the embryo side and on the mother's side there are blood spaces which surrounded the villi.
Functions of placenta. It provides a large surface area for glucose and oxygen to pass from mother's body to the developing embryo. The developing embryo gets its nutrition from placenta. Embryo's waste meterials are passed into the mother's blood for their removal.
