Model on formation of new life

so this is a project on formation of new human life.

so, first of all,i want to tell about the fertilization?

Fertrilization is a epic story of a single sperm facing increible odds to unite with an ovum to form a new human life.

During copulation about 300 million sperms enter the vigina,but due to acidic environment some of them die,and the remaining of them,further move towards the fallopian tube sontaining the unfertilised egg.

To ease the process of fertilisation cilia pushes the ovum towards the uterus.

The first sperm which makes contact will fertilise the ovum.

As soon as single sperm makes contact with the egg,the egg blokes the other sperms,not allowing them to enter inside it.

The two gamete fuse together completing the process of the fertilizaton and new cell, formed is the begining of a new human life.
