Answers
Answer:
Explanation:
The ovaries produce the ova (egg cells). The external sex organs are also known as the genitals and these are the organs of the vulva including the labia, clitoris, and vaginal opening. The vagina is connected to the uterus at the cervix.
a) Fallopian tube
A pregnancy starts with fertilization, when a woman's egg joins with a man's sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing
b) Embryo takes its nourishment from a special disc-shaped tissue embedded in the uterine wall of the mother. It is through this tissue that the nutrients and waste materials are exchanged between mother and foetus. This tissue is known as placenta.
