(b) Name the parts of the human female reproductive system where

Explain how the embryo gets nourishment inside the mother’s body.

(a) Leydig cells of testes produce sperms and secrete a hormone called testosterone.

The function of testosterone is to control the development of male sex organs and secondary male features such as a deeper voice, moustache, beard and more body hair .

(b)
i. Fertilisation takes place in the oviduct or fallopian tubes.
ii. Implantation of the fertilised egg occurs in the uterus.
The foetus gets its nourishment from the special tissue called placenta. After implantation, a disc-like special tissue called placenta develops between
the uterus wall and the embryo. The placenta helps in the exchange of nutrients,
oxygen and waste products between the embryo and the mother. Thus, it
provides nourishment to the growing embryo
