  4. 4. Function of the Excretory System1) To get waste and toxins out of body.2) Helps keep the correct amount ofwater and ions in the body.
  5. 5. Function of the Excretory System1) To get waste and toxins out of body.2) Helps keep the correct amount ofwater and ions in the body.An ion is an atom ormolecule with a positive(+) or a negative (-)charge.
  6. 6. HomeostasisHomeostasis is the body keeping stable.If you have too much of something in yourbody, you will NOT be in homeostasis.Your excretorysystem allowsyour body to stayin a state ofhomeostasis.
  7. 7. OsmoregulationOsmoregulation is moving of ions acrossmembranes to keep the right amountof water (=to keep homeostasis).1) Hypotonic solutions are when there are manyions inside a cell, and water will go IN.2) Isotonic solutions are when water will neither goin or out.3) Hypertonic solutions are when there are manyions outside a cell, and water will go OUT.
