Quizplus · Accepted Answer

Osmotic thirst results from cellular dehydration, which occurs when the concentration of solutes (such as sodium) in the extracellular fluid is higher than the concentration of solutes inside the cells. This can happen when there is not enough water intake or excessive water loss (such as in sweating or diuresis). In contrast, options A and B refer to hypovolemic thirst, which is triggered by a decrease in blood volume or pressure, and option D is not correct, as a decrease in the concentration of extracellular sodium would actually reduce osmotic pressure and alleviate osmotic thirst.
