Osmoregulation 

Organ Systems

Homeostasis Hugs

Questions to answer:

  1. Explain the difference between being a “conformer” and a “regulator”.
  2. Why does an animal need to eliminate nitrogenous waste?
  3. What is the advantage in animals coupling nitrogenous waste excretion to osmolarity regulation?
  4. What considerations determine if an animal excretes nitrogenous waste as ammonia, uric acid, or urea?
  5. Why is reabsorption of molecules from the filtrate required?
  6. Explain how mammals are able to regulate their blood osmolarity through hormonal control.  Diagram the feedback loops involved in this process.
