   Osmoregulation is the process of maintaining salt and water balance (osmotic balance) across membranes within the body. The fluids inside and surrounding cells are composed of water, electrolytes, and nonelectrolytes. An electrolyte is a compound that dissociates into ions when dissolved in water.

   What does osmosis mean?

   • Osmosis refers to the movement of water molecules only. The slideshow shows an example of osmosis showing the direction of movement of water between two different concentrations of sugar solutions. When the concentration of water is the same on both sides of the membrane, the movement of water molecules will be the same in both directions.

   Why do animal cells change size and shape during osmosis?

   • Animal cells also take in and lose water by osmosis. They do not have a cell wall, so will change size and shape when put into solutions that are at a different concentration to the cell contents. For example, red blood cells could:

   How does osmosis affect the level of solution 2?

   • In theory, the level of solution two will rise, but this will be opposed by gravity and will be dependent on the width of the container. , for instance, salt instead of sugar. is partially permeable. Water will move into and out of cells by osmosis. Isolated plant cells placed in a dilute solution or water will take in water by osmosis.

   How do mammalian systems regulate osmotic pressure?

   • Mammalian systems have evolved to regulate not only the overall osmotic pressure across membranes, but also specific concentrations of important electrolytes in the three major fluid compartments: blood plasma, extracellular fluid, and intracellular fluid.

   Are fish osmotic?

   • They are incapable of osmotic regulation in the opposite environment. It is possible, however, for a few fishes like salmon to spend part of their life in freshwater and part in seawater. Organisms like the salmon and molly that can tolerate a relatively wide range of salinity are referred to as euryhaline organisms.

   How do animals achieve isotonicity with the sea?

   • They achieve isotonicity with the sea by storing large concentrations of urea. These animals that secrete urea are called ureotelic animals. TMAO stabilizes proteins in the presence of high urea levels, preventing the disruption of peptide bonds that would occur in other animals exposed to similar levels of urea.
