Answer:
Osmoregulation means the maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentrations.
Histamine is an organic nitrogenous compound involved in local immune responses, as well as regulating physiological function in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. Histamine is involved in the inflammatory response and has a central role as a mediator of itching.

Chemical formula: C5H9N3
Acidity (pKa): Imidazole: 6.04; Terminal NH2: 9.75
Solubility in water: Easily soluble in cold water, hot water
Melting point: 83.5 °C (182.3 °F; 356.6 K)
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 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 osmosis.[1] The higher the osmotic pressure of a solution, the more water tends to move into it. Pressure must be exerted on the hypertonic side of a selectively permeable membrane to prevent diffusion of water by osmosis from the side containing pure water.
