Male Reproductive System

The human male reproductive system is adapted for the production of

• sperm and the delivery of these cells for internal fertilization

• gametes that transport food to the egg

• zygotes and the development of these cells into a fetus

• hormones that stimulate placenta formation in the male

A reproductive system is represented in the diagram

given. Which structure is correctly paired with its

reproductive function?

• A – pathway of gametes

• B – synthesis of progesterone

• C – production of sperm

• D – regulation of homeostasis

The primary function of the human male reproductive

system is to

• provide a site for fertilization

• produce and transport gametes

• protect and nourish the embryo

• prevent urine from leaving the body

A diagram of the human male reproductive system is given. Which structure produces cells that have the potential to become gametes?

• A

• B

• C

• D

Which structure is correctly paired with its function?

• ovary — provides milk for newborns

• testis — development of sperm

• placenta — storage of released eggs

• uterus — produces estrogen

The reproductive system of a male mammal provides

• support for the internal development of the

  embryo

• materials through the placenta

• a means for the delivery of gametes

• the ovaries for gamete production

Base your answer to the following question on the diagram given and on your knowledge of biology. The letters in the diagram indicate structures present in a human male.

What change would occur immediately if both

structures labeled B were damaged or blocked?

• Structure A would decrease in size.

• The blood supply to structure E would decrease.

• Gametes would no longer be transported to

  structure C.

• Structure D would be able to deliver more

  gametes.

The diagram given represents the human male reproductive system. Which activity would be prevented by blockages at X

and Y?

• transport of urine out of the body

• passage of testosterone to the female to stimulate

  egg production

• movement of sperm out of the body

• movement of testosterone to the testes to

  stimulate sperm production

The diagram given represents a system in the human

body. The primary function of structure X is to

• produce energy needed for sperm to move

• provide food for the sperm to carry to the egg

• produce and store urine

• form gametes that may be involved in

  fertilization

Base your answers to questions 10 on

the picture given which represents systems in a

human male and on your knowledge of biology.

Which structure has both reproductive and

excretory functions?

• A

• G

• C

• D
