Male and Female Reproductive Systems

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

Which structure produces gametes during the process of meiosis?

• 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

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.
