Diuresis used to increase urine output and decrease extracellular fluid volume. Substances in the circulation can also increase the amount of circulating fluid by increasing the osmolarity of the blood. This has the effect of pulling water from the interstitial space, making more water available in the blood and causing the kidney to compensate by removing it as urine. In hypotension, often colloids are used intravenously to increase circulating volume in themselves, but as they exert a certain amount of osmotic pressure, water is therefore also moved, further increasing circulating volume. As blood pressure increases, the kidney removes the excess fluid
Blood is thicker than water Trumbull notes an interesting comparison of blood and milk in the Arab world: More recently, Aldous Huxley's "Ninth Philosopher's Song" (1920) approached the proverb differently, stating, "Blood, as all men know, than water's thicker / But water's wider, thank the Lord, than blood."
