Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: The Male Reproductive System

Level#1: The male reproductive system has two jobs. It must first make sperm cells. Sperm cells are male reproductive cells. The male reproductive system also delivers sperm to the female reproductive system. Sperm cells are made in organs called testes. The testes are in a sack of skin called the scrotum. To stay alive, sperm must be kept cooler than other parts of the body. The scrotum is outside the body so it keeps the sperm cool.

1. How many jobs does the male reproductive system have?





2. What are the two jobs of the male reproductive system?





3. Where are sperm cells made?







Level#2: The male reproductive system has two jobs. It must first make sperm cells. Sperm cells are male reproductive cells. The male reproductive system also delivers sperm to the female reproductive system. Sperm cells are made in organs called testes. The testes are in a sack of skin called the scrotum. To stay alive, sperm must be kept cooler than other parts of the body. The scrotum is outside the body so it keeps the sperm cool. Sperm travel from the testes through thin tubes called sperm ducts. These ducts carry the sperm to the urethra. As the sperm move down the sperm ducts and urethra, three glands add fluids to it. The mixture of sperm and fluid is called semen. The penis delivers the sperm to the female reproductive system.

The male sex hormone is testosterone. Testosterone causes facial hair and body hair to grow. It causes boys' bodies to become more muscular. Testosterone also causes boys' voices to become lower.

1. Explain what the two jobs of the male reproductive system are.





2. Explain where sperm cells are made, where the testes are located, and what must happen to keep sperm alive.






3. Explain why the scrotum is located outside the body.
