INTRODUCTION
This video is designed for use in grades 6 - 9 as an introduction to the major ideas and concepts associated with the human excretory system, and for use in grades 10 - 12 as review.
PROGRAM OBJECTIVES
After viewing the video and participating in the accompanying activities, the students will be able to achieve the following objectives:
• Describe the function and workings of the excretory system.
• Identify the main parts of the excretory system.
• Identify the way the kidneys filter the blood.

SUMMARY OF THE VIDEO
This video describes the functions of the excretory system.
The excretory system is critical to survival. The trillions of living cells in the human body produce metabolic wastes which must be eliminated from the body. If the wastes aren’t eliminated, it might lead to death. These wastes include carbon dioxide, urea, water, water vapor, and salts.
There are four organs that make up the excretory system: the lungs, kidneys, liver, and skin.
