What happens to a fertilized egg when it reaches the uterus?

Question

I was just wondering what happens the fertilized egg on the way to and when it reaches the uterus. Where in the uterus does the egg stay after it gets there? How long does it stay there? What happens to it during that time?

Thank you in advance.

Answer 1

The fertilized egg, or embryo, travels down the fallopian tube to the uterus where it burrows into the uterine lining. This is called implantation . The time between fertilization and implantation is approximately six days. After implantation, the body begins producing a special pregnancy hormone called human chorionic gonadotropin (HCG) that can be detected by a home pregnancy test.

Answer 2

Nothing happens on the way to when it reaches the uterus.after it reaches uterus it accepts the fertilized ovum (egg)which becomes implanted into the endometrium, and derives nourishment from blood vessels which develop exclusively for this purpose.

The fertilized ovum becomes an embryo, develops into a fetus.It develops from the end of the eighth week after fertilisation, when the major structures and organ systems have formed and gestates until childbirth.

Birth is imminent and occurs around the 40th gestational week. The fetus is considered full-term by week 35, which means that the baby is considered sufficiently developed for life outside the womb.

Due to anatomical barriers such as the pelvis, the uterus is pushed partially into the abdomen due to its expansion during pregnancy.

Answer 3

Assuming you are talking about a human fertilized egg...(although this is true for any placental mammal)...Once a fertilized egg reaches the uterus, it has already gone through many cell divisions and is actually a small ball of cells called a blastula and is referred to at this point as a zygote. The zygote will attach to the wall of the uterus in the blood vessel rich surface called the endometrium. The endometrium is the source of the menstrual flow. Where the zygote attaches is totally random. A major structure develops from this growing ball of cells that forms the placenta and umbilical cord. The developing zygote eventually forms a fetus. During the developmental time for the zygote, rapid cell divisions begin forming the more familiar structures of our organs, limbs, skeleton, and other tissues. The fetus will eventually be given birth to at the end of about 9 months. Hopefully a healthy baby boy or girl is the end result.

Answer 4

well, the fertilized egg proudces hormones that help it attach to the uterine wall, at this point, it becomes a fetus. the trip from fallopian tube to uterus takes 6 days. after attaching to the uterine wall, the walls of the womb contiue to develop, and a chemical "plug" is produced by the uterus, to keep invading sperm out. then, the fetus begins to develop.

Answer 5

It attaches to the wall to get nutrients, divides over and over eventually turns into a baby, it stays there for 40 weeks.
