Many organisms living in the oceans or in salt lakes are hyporegulators, meaning that they maintain their body fluids hypo-osmotically to the external medium. Marine fish hyporegulate by drinking the external medium and transporting sodium and chloride ions outward across the gills.

What is meant by term osmoregulation?
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body ...
What are Hyperosmotic regulators?
FRESHWATER hyperosmotic regulator. organism that regulates osmotic pressure above environment, all freshwater animals, all freshwater animals gain water and lose ions. rate of exchange dependent upon. magnitude of ionic & osmotic gradients, permeability of animal integument, surface area of exchange surface.
What is osmoregulation in the kidney?
Osmoregulation is the homeostatic control of the water potential of the blood. The kidneys are involved in filtering the blood and deciding which substances to reabsorb and which to excrete as waste. Tiny tubular structures known as tubules carry out this filtration.
Why are kidneys referred to as Osmoregulatory structures?
Kidneys regulate the osmotic pressure of a mammal's blood through extensive filtration and purification in a process known as osmoregulation. All the blood in the human body is filtered many times a day by the kidneys. ... Kidneys eliminate wastes from the body; urine is the filtrate that exits the kidneys.
What is osmoregulation in biology class 10?
The process by which an organism regulates the water balance in its body and maintains the homeostasis of the body is called osmoregulation. It includes controlling excess water loss or gain and maintaining the fluid balance and the osmotic concentration, that is, the concentration of electrolytes.
What is meant by the term osmoregulation Class 11?
“Osmoregulation is the process by which an organism regulates the water and electrolytic balance in its body to maintain homeostasis.”
What is the difference between Hyperosmotic and Hypoosmotic?
The key difference between isosmotic hyperosmotic and hypoosmotic is that isosmotic refers to the property of having equal osmotic pressures, but hyperosmotic refers to the property of having a high osmotic pressure. Meanwhile, hypoosmotic refers to the property of having a low osmotic pressure.
What does Hyperosmotic mean?
Hyperosmotic (biology definition): (1) of, relating to, or characterized by an increased osmotic pressure (typically higher than the physiological level); (2) a condition in which the total amount of solutes (both permeable and impermeable) in a solution is greater than that of another solution. ...
Does Hyperosmotic mean hypertonic?
Hyperosmotic solutions are not always hypertonic. But hyposmotic solutions are always hypotonic. ... If the solution has a lower concentration of nonpenetrating solutes than the cell does, then there will be net movement of water into the cell at equilibrium and the solution is hypotonic.
How Osmoregulatory feedback mechanism happens in our body?
Osmoregulation is an example of a negative feedback, homeostatic control system. This system detects changes in the salinity of the water Chinook salmon live in, working to keep the body water concentration constant.
What are the Osmoregulatory organs in human?
The kidneys are the main osmoregulatory organs in mammalian systems; they function to filter blood and maintain the osmolarity of body fluids at 300 mOsm. They are surrounded by three layers and are made up internally of three distinct regions—the cortex, medulla, and pelvis.
What is an artificial kidney give its significance?
In case of kidney failure, an artificial kidney can be used. An artificial kidney is a device to remove nitrogenous waste products from the blood through dialysis. Artificial kidneys contain a number of tubes with a semi-permeable lining, suspended in a tank filled with dialysing fluid.
Where is osmoregulation detected?
Kidneys. The kidneys are organs of the urinary system - which removes excess water, mineral ions and urea. Our bodies can control the amount of water and ions removed by the kidneys. This is called osmoregulation.
