• C. Uterus
• D. Vestibule

Answer 1

Answer: (B)

• Fertilization takes place in the oviduct.

Oviduct is also called a Fallopian tube.

• Oviduct is where most fertilization happens for humans. It can occur in the upper portion of the uterus or it could even happen on the outside of the reproductive tract in the event of inflammatory disease in the pelvic region. This would create an ectopic pregnancy which is a serious occurrence.

The menstrual cycle gets the woman's body ready and about halfway through human fertilization begins. The egg reaches ovulation and is released into the oviduct where fertilization will take place.

• If the egg becomes fertilized no other sperm is able to penetrate the egg. The genes of the baby are determined the moment the egg is fertilized. Sperm with a Y chromosome means it's a boy and an X chromosome it's a girl.

While the egg remains in the oviduct for up to 4 days it starts to divide into cells just 24 hours once it has been fertilized. The main focus of the egg is to implant itself into the side of the uterus. After about 3 weeks the first nerve cells of the baby have been formed.
