Module 8—Circulation, Immunity, and Excretion

Lesson 9—Maintaining the Excretory System

 

Get Focused

 

After drinking a thirst-quenching glass of water, have you ever considered that a water treatment plant determines specific levels of minerals and ions acceptable for tap water?  Since water is essential for humans to drink, having too many chemicals and salts in water is not healthy.


Water treatment plants take this into account and try to balance the chemicals necessary to make water safe to drink, yet healthy for humans to drink.


Your kidneys play a similar role. The kidneys ensure that your water and ion levels are maintained. How do the kidneys react if you drink too much or too little water?

 

In this lesson you will explore the following questions:

  • How do the kidneys contribute to homeostasis in terms of water and ions?
  • How does the design of the kidney relate to dialysis technologies?
