Reproductive System

A fertilized egg undergoes several stages before it is successfully implanted. The diagram below shows these stages as the fertilized egg travels through the female reproductive system.

In which of the following structures of the female human reproductive system is the blastocyst implanted during normal human development?

• ovary

• uterus

• vagina

• amniotic sac

The drinking of alcoholic beverages by a pregnant woman is harmful to the development of her fetus. This is most damaging early in a pregnancy because during this time

• the lungs of the fetus become functional.

• alcohol can easily enter the mouth of the fetus.

• many of the essential organs of the fetus are forming.

• the fetus cannot excrete wastes.

• It forms into a blastocyst

• It is an unfertilized egg

• It produces haploid male gametophytes

• It is a fertilized egg

Which of the following describes fertilization?

• cell differentiation to form a blastula

• formation of germ layers in a deuterostome

• a sperm joining an egg to form a zygote

• sperm and egg production

Structure 4 is the

• uterus
• ovary

What is structure #3

• Ovary
• Fundus
• Fallopian Tube
• I don't know

What is the main role of FSH?

• Stimulates follicle to burst and release the ovum
• Stimulates rebuilding of the uterus wall
• Stimulates one egg cell to develop (become follicle)
• Completes development of uterus wall, promotes glycogen storage

Sexual reproduction is vital to the propagation of the Human race. Which of the following sequences represents the correct order of events in the formation of a human fetus?
