osmoregulation is the regulation of water content in the body. It controls the permiability of the walls of the collecting duct.
What else can I help you with?
What are some examples of osmoregulators?
Examples of osmoregulators include marine invertebrates such as crabs and lobsters, as well as freshwater fish like trout and salmon. These organisms actively regulate their internal solute concentrations to maintain osmotic balance with their environment.
What is the difference between osmoregulators and osmoconformers?
Osmoconformer adjusts to the osmotic concentration of its surrounding so that the osmoregularity is the same at the medium. Osmoconformer maintain its own osmotic concentration regarldess of the surrounding medium.
How can saltwater organisms survive in their saltwater environment?
By osmoregulation. Differs by species or type of organism, but they are either osmoconformers or osmoregulators.
Marine animals that have body fluids with a solute concentration equal to that of the surrounding seawater are said to be?
osmoconformers
How does the salmon function as a good osmoregulator?
Salmon are good osmoregulators because they can maintain a proper water balance in their bodies in both salt water and freshwater. This change in environment doesn't cause them to die.
What is difference between osmoconformer and osmoregulator?
Osmoregulator have to use energy to gain or loss water, because their body fluids are different from their environment.(osmoregulation is the process an organism uses to balance the fluids/water)Osmoconformer, on the other hand is, are organisms that have body fluids that are the same as its environment.(They don't gain or loss water during osmosis. Therefor they don't have to worry about using energy to combine ammonia with carbon dioxide ---because they excrete ammonia)
What marine organisms whose internal salt concentration varies with that of their environment are examples of?
Marine organisms that maintain their internal salt concentration to match their environment are known as osmoconformers, such as jellyfish, sea anemones, and some bivalves. These organisms allow their internal salt concentration to vary with the surrounding seawater to avoid losing excessive water or becoming dehydrated.
What is transported in the plasma?
Ions: sodium, chlorine, pottasiu, calcium; buffers and osmoregulators; also hormones are transported in the blood plasma.
What fish live in salt water?
salt water crocodiles do, and can go from fresh to salt water at will.
What is the form of enantiostasis in estuarine organisms?
With the help of Enantiostasis an estuarine organism is able to maintain metabolic functions while withstanding the extreme fluctuation in conditions. Organisms that do this are called osmoconformers and osmoregulators. Two major types of osmoregulation are osmoconformers and osmoregulators. They apply to both plants and animals. Osmoregulation is the active regulation of the osmotic pressure of an organism's fluids to maintain the homeostasis, or equilibrium, of the organism's water content; that is it keeps the organism's fluids from becoming too diluted or too concentrated. These organisms are unable to tolerate a range of salt concentrations in their body fluids and so avoid changes in their internal environment by keeping the solutes at an optimum level. Fast-swimming organisms such as fish overcome this variation by moving away during a change in the salt concentration of the water. Most molluscs can close their shells and wait until the external environment is favourable again. Bottom-dwellers can burrow into the mud or sand. Another example is freshwater fish. The gills actively uptake salt from the environment by the use of mitochondria rich cells. Water will diffuse into the fish, so the fish excretes very hypotonic (dilute) urine to expel all excess water. Osmoconformers work differently, almost opposite to osmoregulators in fact. As the name suggests they conform to the surrounding environment by altering the concentration of their internal solutes. Their metabolic processes are able to tolerate any changes in salinity in their own body fluids and cells, a contrast to osmoregulators.A marine fish for example, forrfhas an internal osmotic concentration lower than that of the surrounding seawater, so it tends to lose water and gain salt. It actively excretes salt out from the gills and very hypertonic (concentrated) urine. Plants in mangroves and coastal marshes, also known as Halophyes, live in the boundary between salt and fresh water. However since plants cannot move, they overcome this variation in the ecosystem by means of salt barriers, secretion of salt and salt deposits. Secretion is when some plants concentrate salt and get rid of it through special glands on the leaves, often very visible as you can see. Such examples include the Grey or River Mangroves. Salt deposits are where salt is usually deposited in older tissues, branches or leaves which are then discarded in order to get rid of the salt. Salt barriers are special tissues in the roots and lower stems that stop salt from entering the plant but still allows water uptake.
