CAS BI 108 Chapter Notes - Chapter 44: Osmoregulation, Osmotic Concentration, Extracellular Fluid
Document Summary
Identify different types of nitrogenous waste and excretory systems. Explain how kidneys use nephrons to eliminate waste. Distinguish between hormones that regulate waste excretion. Animals must regulate the amount of fluids and salts in their various tissues through a process known as osmoregulation. As a part of this process animals must eliminate otherwise toxic nitrogen waste compounds through various forms of excretion. Osmoregulatory marine animals can help to balance their osmolarity by drinking large. Osmoregulation involves the homeostatic control of solute concentrations within biological. 44. 1 basics of osmoregulation fluids such as the blood. Solute concentration in a given solution is measured in terms of osmolarity. Animals may either be osmoconformers that are isosmotic with their surroundings or osmoregulators which actively alter their osmolarity without regard to the surrounding environment. Sharks have a unique means of maintaining slightly elevated osmolarity due to the presence of specific proteins and salts in their blood.
