11. The 290 is the value of the stool osmolality . 12. Plasma osmolarity / osmolality is important for keeping proper electrolytic balance in the blood stream. 13. A decrease in osmolality after spawning in fresh water makes a cyprinid fish s sperm motile. 14. Osmolality can reach up to 1400 mOsmol / kg by the end of the descending limb.15. Why does the concentration of sodium atoms contribute 36 times more to the osmolality than glucose? 16. The osmolality in the plasma is lower than the surrounding water, which is dehydrating for the animal. 17. In normal people, increased osmolality in the blood will stimulate secretion of antidiuretic hormone ( ADH ). 18. Plasma osmolality with typical fluid intake often averages approximately 290 mOsm / kg H 2 O in humans. 19. Hence, less water is reabsorbed, thereby increasing urine output, decreasing urine osmolality , and normalizing blood osmolality. 20.
