Question

(a) Name the respective part of the human female reproductive system.
A. That produces eggs.
B. fusion of egg and sperm takes place
C. zygote gets implanted.
(b) Describe in brief what happens to the zygote after it gets implanted.

Answer 1

Hint: In sexually reproducing animals such as human, the male produces sex gametes known as the male germ cells and the female produces the ovum. THe ovum or the egg fuses with the male sperm and undergoes the process of fertilization. Fertilization is an important part for the reproduction of the offspring.

Complete answer:
The reproductive system in the females consists of internal as well as external organs that are specific to the female sex and are known as sex organs. The sex organs function in the process of fertilization and reproduction of the child. In females, the reproductive system matures at a certain age known as puberty and is able to produce the ovum. With the onset of puberty, the females undergo cyclic reproductive cycles which are known as the menstrual cycle. The internal sex organs of the females are the uterus, fallopian tubes, ovaries.
The ovaries are the organs that are associated with the production of the eggs or the ova. They are small, paired organs that are located near the lateral walls of the pelvic cavity. In addition to the production of eggs, they also produce certain hormones. The release of the ovum from the ovary takes place through a process known as ovulation.
After being released, the ovum travels to the fallopian tubes which are two tubes that lead from the ovaries and the uterus. When in the fallopian tube, the ovum is able to become fertilized by a sperm. Fertilization of the ovum takes place in the fallopian tubes by the sperm.
The fertilized zygote is then received by the uterus which is also known as the womb. It is the part of the reproductive system that provides support, protection and nutrition to the growing embryo. In the uterus, the zygote is implanted and establishes blood vessels to form connections to the endometrium lining of the uterus and it creates a placenta.
The zygote formed is a developing embryo and gets attached to the lining of the uterus. It receives two sets of chromosomes, one from each parent. After implantation, the zygote divides rapidly to form a mass of cell and is known as an embryo. It forms close connections with the internal vessels of the uterus and derives nourishment and oxygen from it. Finally, in the next two months the different body parts are developed and the embryo is now called the fetus. It completes about nine months in the uterus and finally after complete development, the mother gives birth to the child.

Hence, the correct answer is option (B).

Note: The internal reproductive system of the females consists of three important organs which are the uterus, fallopian tubes and the ovaries. THe ovaries are the site which gives rise to the ovum which is fertilized by the male sperm in the fallopian tube. From the fallopian tubes, the fertilized zygote then reaches the uterus where it gets implanted to continue further until child birth. The uterus provides all the nutrition and oxygen to the developing embryo.
