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 

• ovary
• uterus
• vagina
• amniotic sac

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

Below is a diagram of the male reproductive system. Which structure is represented by the letter D? 

• scrotum
• testes
• prostrate gland
• epididymus

Abnormalities present in the cells that line the uterus may prevent the production of offspring by directly interfering with which process? 

•  the development of the embryo
• the differentiation of gametes into zygotes
• the secretion of estrogen by the ovary
• the production and release of egg cells

What is the human embryo called after the eighth week of development?

• zygote
• an infant
• a fetus
• a morula

For a human zygote to become an embryo, it must undergo

• fertilization
• recombination
• meiotic dvisions
• mitotic divisions

The diagram below represents a stage in the development of a fetus. A major function of structure X is to

• produce gametes by meiosis
• protect the fetus from physical injury
•  exchange materials between the mother and the fetus
• store food to provide the fetus with nutrients

Look at the picture and match the following

• Pituitary Gland

• B

• Brain Stem

• A

• Pons

• C

• Cerebellum

• E

Which part is the ovary?

• 5

• 3

• 4

• 6

What is the function of the human male reproductive system?

• grow and develop baby

• produce egg and deliver egg to female

• internal fertilization

• produce sperm and deliver sperm to female
