It starts growing.....into a baby........
It's usually fertilized in the Fallopian tube, travels down into the uterus where it attaches to the wall there
"Period" is a term for menstruation ... the biological cleaning out of the endometium (inner lining) of the uterus - done to prepare the uterus to receive the fertilized egg. The fertilized egg "implants" (sticks to) the wall of the uterus and develops into a fetus (complete with placenta) which will eventually be born as a child.
If an egg is not fertilized by the time it reaches the uterus, it will disintegrate and be absorbed by the body. The uterus will shed its lining during menstruation, which includes the unfertilized egg.
A fertilized egg implants into the Uterus.
An egg gets fertilized in the fallopian tube by a sperm, then it goes inside of the uterus, and inside the uterus it develops.
Progesterone is the hormone that works with estrogen to prepare the endometrium for implantation of a fertilized egg. It helps thicken the lining of the uterus and maintain a suitable environment for pregnancy.
If an egg is fertilized, it can develop into an embryo and eventually a fetus if implanted in the uterus. If an egg is not fertilized, it will disintegrate and be shed along with the uterine lining during menstruation.
The blood lining of the uterus gradually thickens during a woman's menstrual cycle in order to be prepared to receive the fertilized egg. This lining will shed during the menstrual period if no fertilized egg has implanted.
A fertilized egg before it implants in the uterus is called a zygote. Once it implants in the uterus, it is referred to as a blastocyst.
The uterus is the part of the female reproductive system that nourishes and develops the fertilized egg. After fertilization, the egg implants in the lining of the uterus where it continues to grow and develop into a fetus.
If the egg is not fertilized it disintegrates (breaks down) and menstruation (your period) begins 11-16 days later. The mature egg is fertilized when it is joined with a sperm cell.
