With the help of a flow chart depict the steps in the stages of fertilization in humans?

Dear student,




The above picture shows the process of fertilisation. Once the ovum is released from the ovary, it fuses with the sperm at the ampulla region of the fallopian tube. Although many sperm cells come for the fusion with the egg cell, only one is able to fertilise it (the sperm induces changes in the zona pellucida of the ovum). Once a sperm cell has entered into the ovum, there is formation of a layer around the ovum which prevents further entry of any other sperm. Fertilisation thus becomes completed and a zygote is formed, which is now ready to get implanted into the uterus.
 
Regards.
