In the given figure label the parts and mention their functions
i. Production of egg

ii. Site of fertilisation

iii. Site of implantation

iv. Entry of the sperms

Answer :

Production of egg - Ovary


Ovaries are the female reproductive organs in which the female germ cells or eggs are produced. They are also the organs responsible for the secretion of the hormones estrogen and progesterone that maintain the eggs and impart the secondary sexual characters in females.

ii. The site of fertilization - Fallopian tube


The fallopian tube is the region that receives the egg after it is released from the ovary for fertilization. The sperm travels through the vagina and the uterus towards the fallopian tube in which the egg is present for fertilization by the sperm. The fallopian tube then transfers the fertilized egg to the uterus for implantation.

iii. Site of implantation - Inner lining of the Uterus


The inner lining of the uterus is the site where the fertilized egg, known as the zygote gets implanted. The tissues in the inner lining are modified to implant the zygote and have many blood vessels to nourish the embryo that grows from the zygote

iv. Entry of the sperms Vagina


The vagina provides the opening for the entry of sperms through the male penis after sexual intercourse. The sperms travel through the vagina and then the uterus towards the fallopian tube where fertilization of egg takes place.
