what is imlpantation?
Answers
While studying about the topic, "Reproduction In Animals", we should have the knowledge about two simple terms, namely, FERTILISATION and IMPLANTATION.
Here, I will say about both of them.
[1] FERTILISATION : During sexual intercourse, the semen can get deposited in female's vagina. The sperms are released in the vagina and they actively swim upwards with the help of their tell. Out of millions of sperms released into the vagina, only a few of them are able to climb up to the upper parts of oviducts. The rest die on the way and gets absorbed. If there happens to be an egg in the oviduct, it gets fertilised by just one single sperm. So, ultimately, we can say, the process of fusion of the nucleus of sperm with the nucleus of the egg to form a zygote is known as fertilisation.
[2] IMPLANTATION : The fertilised egg soon starts developing and by the time it reaches the uterus, a small ball of numerous cells is already formed. This is a kind of embryo which forms a pit in the uterus wall and gets fixed in it. This natural way of fixing of the embryo in the wall of the uterus is called implantation which, in turn, produces the state of pregnancy.
