• testis
• urethra
• vas deferens
• prostate

What is the name of the structure labeled #3 where sperm is stored?

• testis
• epididymis
• scrotum
• seminal vesicle

What is the name of the structure labeled #3 where sperm is stored?

• testis
• epididymis
• scrotum
• seminal vesicle

Name the structure that produces a thin milky fluid that aids in sperm motility and contributes to about 30% of overall semen volume.

• testis
• seminal vesicle
• prostate gland
• bulbourethral gland

Name the large oval structure seen here inside the testis.

• seminal vesicle
• seminiferous tubule
• spermatogonium
• epididymis

What organelles are abundant in sperm cells to provide energy for flagellum movement?

• ribosomes
• lysosomes
• enzymes
• mitochondria

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 is correctly paired with its function?

• ovary — provides milk for newborns

• testis — development of sperm

• placenta — storage of released eggs

• uterus — produces estrogen

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 question 11 on the picture given which represents systems in a human male and on your knowledge of biology.

Which structures aid in the transport of sperm by

secreting fluid?

• A and H

• B and E

• C and D

• D and H
