Explain the mechanism of fertilization and implantation of foetus in the uterus. |
|
Answer» During fertilization, the sperm and egg UNITE in one of the fallopian TUBES to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then BURROWS into the uterine lining — a process called implantation. |
