Answer:

(a)

ovary: The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.

oviduct:(ii) Oviduct also known as fallopian tubes. Functions: 1) To transfer the female gametes (egg) from ovary to uterus. 2) The fertilization of egg (or ovum) by a sperm takes place in the oviduct

Uterus : The uterus is a pear-shaped muscular organ. Its major function is to accept a fertilized ovum which becomes implanted into the endometrium, and derives nourishment from blood vessels which develop exclusively for this purpose. The fertilized ovum becomes an embryo, develops into a fetus and gestates until childbirth.
