Examples of osmoregulation in the following topics:

  • Osmoregulators and Osmoconformers

    • Aquatic organisms with various salt tolerances adapt to their environments through osmoregulation and osmoconformation.
    • Fish are osmoregulators, but must use different mechanisms to survive in (a) freshwater or (b) saltwater environments.
  • Introduction to Osmoregulation

    • Osmoregulation balances concentrations of solutes and water across semi-permeable membranes, maintaining homeostasis.
    • Osmotic regulation, or osmoregulation, keeps these solutes at the ideal concentrations.
    • Osmoregulation is the process of maintenance of salt and water balance (osmotic balance) across membranes within the body's fluids, which are composed of water plus electrolytes and non-electrolytes.
    • Osmoconformers are marine animals which, in contrast to osmoregulators, maintain the osmolarity of their body fluids such that it is always equal to the surrounding seawater.
    • Excess electrolytes and wastes that result from osmoregulation are transported to the kidneys and excreted.
  • Osmoregulation

    • Osmoregulation is the process by which living things regulate the effects of osmosis in order to protect cellular integrity.
    • Various living things have ways of controlling the effects of osmosis—a mechanism called osmoregulation.
  • Other Hormonal Controls for Osmoregulation

  • Concept of Osmolality and Milliequivalent

    • Osmoregulation maintains body fluids in a range of 280 to 300 mOsm.
  • Steroids

    • Cholesterol also plays a role in synthesizing the steroid hormones aldosterone, which is used for osmoregulation, and cortisol, which plays a role in metabolism.
  • Contractile Vacuoles in Microorganisms

    • A contractile vacuole (CV) is an organelle, or sub-cellular structure, that is involved in osmoregulation and waste removal .
  • Kidney Structure

    • Kidneys regulate the osmotic pressure of a mammal's blood through extensive filtration and purification in a process known as osmoregulation.
  • Phylum Nemertea

    • A pair of protonephridia, or primitive kidneys, is present in these animals to facilitate osmoregulation.
  • Gnathostomes: Jawed Fishes

    • Skin glands secrete mucus that reduces drag when swimming and aids the fish in osmoregulation.
