1. Write the functions of each of the following parts in a human female reproductive system:
   1. Ovary
   2. Uterus
   3. Fallopian tube
2. Write the structure and functions of placenta in a human female.

(a)

(i) Ovary: The function of the ovary is to produce one egg every month. It is also responsible for the production of female hormones.

(ii) Uterus: The function of the uterus is to prepare itself every month by thickening the endometrium lining of the uterus to receive a fertilized egg or a zygote. Thus, the embryo gets implanted in the soft lining of the uterus. The embryo implantation helps in the further development of the embryo and also to obtain nutrients and oxygen required for its development.

(iii) Fallopian tube: The fallopian tubes, also known as uterine tubes or oviducts, are the female structure that allows the transport of eggs from the ovary to the uterus. It is the structure where the fertilization of egg and sperm takes place.

(b) Placenta is the life support system of a fetus (as it helps to exchange the oxygen, nutrients, and waste materials between mother and fetus).

The placenta is a complex, circular tissue-like organ that forms the connection between the uterus wall and an embryo after the implantation.

In a pregnant female, the umbilical cord joins the embryo to the placenta. Plancenta's main function is to exchange nutrients, oxygen, and waste product between an embryo and mother.
