7.3 Get the Facts: Male Reproductive System
Using the chart illustrated on Site 1, carefully research the functions of the numbered structures. Please note how one organ functions with another organ. The online assessment will require definitions for each structure. Be sure to take the time to do the necessary research.
Section 1, Site 1
- Seminal vesicle:
- Vas deferens:
- Prostate gland:
Section 2, Site 3
Carefully route the path the sperm takes from initial development to exit from the body.
- Sperm are produced in the testes.
- Sperm travel from the testes to the epididymis where they mature.

First, 1. ___ are produced in the small seminiferous tubules of the
- _ _. These oval-shaped glands are protected by a sac called the
3.. After the sperm cells are produced, they are stored in a large coiled tube that is located on the outer portion of the testes called the
- _. During times of sexual arousal, the sperm begin to leave the epididymis and travel into long tubes called the 5. _ _.
Along the way, sperm journey through the 6. _ __where they are nourished by a sugary fluid. In addition, they receive a chemical fluid from the 7. _ _ which is the most common site of cancer in men.
These fluids plus the sperm cells combine to form 8. _ _.
At this point, the 9. _ _, which is a tube that carries the sperm outside the body, meets the prostate gland. Before a male can ejaculate, the spongy tissue surrounding the penis called 10. _ _becomes engorged with blood causing the penis to become stiff and hard. A valve like structure now restricts the flow of urine from the bladder and the sperm continues its journey through the urethra and is ejaculated from the penis.
Label the numbered parts of the male reproductive system. Use the drawing found in Section 3 of the online lesson.
