What would happen if fertilization does not occur?
Reginaldward54fb0786
After puberty, the ovaries release one egg each month alternatively.
The sperms enter through the vagina, travel upwards to the oviduct where they encounter the egg.
If the egg is fertilized, a zygote is formed. The zygote repeatedly divided to form the embryo. This embryo trickles down to the uterus. On the uterine wall, the embryo gets implanted.
The embryo gets nutrition form a special disc shaped tissue towards the uterine wall called the placenta. It contains villi on the embryo's side and provides nourishment and oxygen from the mother's blood. Waste substances such as carbon dioxide and nitrogenous wastes are taken away from the embryo.
After the 9 month gestation period, the child is delivered as a result of rhythmic contractions of the uterus.
