  • Overview of the Urinary System

    • The kidneys play a very large role in human osmoregulation by regulating the amount of water reabsorbed from the glomerular filtrate in kidney tubules, which is controlled by hormones such as antidiuretic hormone (ADH), renin, aldosterone, and angiotensin I and II.

  • Circumventricular Organs

  • Fluid Compartments

    • The concentrations of ions such as sodium and potassium are generally lower in the cytosol comapred to the extracellular fluid; these differences in ion levels are important in processes such as osmoregulation and signal transduction.
