WebWhen two solutions differ in osmolarity, the solution with higher concentration of solute is called hypertonic, while the more dilute solution is called hypotonic. If a semipermeable membrane separates such solutions, the flow of water (osmosis) takes place from a hypotonic solution to a hypertonic one.

Fine control of the precise amount of water and salt reabsorbed into blood is an important function of the distal convoluted tubules and collecting ducts. Depending on the need of the water in the body, kidneys excrete hypotonic (dilute) or hypertonic (concentrated) urine. …
WebOsmoregulation 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. An electrolyte is a solute that dissociates into ions when dissolved in water. Web22 jun. 2016 · These results support the notion that the cost of osmoregulation is probably common in most animal species and suggest the existence of a functional association …

Shellfish are aquatic invertebrates with exoskeletons that are consumed as food. Crustaceans and mollusks such as shrimp, squid, oysters, scallops, crabs, lobster, and snails are examples of shellfish. The majority of shellfish live in saltwater, but the name also includes freshwater species. tow summit 2022Osmoregulation 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 fluid) to keep the body fluids from becoming too diluted or concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by tow summit 2023
