: As [[blood]] passes through the [[kidney]]s [[water]], [[urea]], [[glucose]] and [[salt]]s [[Diffusion|diffuse]] into the [[Kidney Tubule|kidney tubules]]. [[Glucose]] is completely reabsorbed into the [[blood]] while [[water]] is selectively reabsorbed depending on the [[water]] [[concentration]] in the [[blood]].: The selective reabsorption re-absorption of [[water]] is affected by [[Anti-diuretic Hormone|anti-diuretic hormone]]. When the levels of [[Anti-diuretic Hormone|anti-diuretic hormone]] are high most of the [[water]] is reabsorbed into the [[blood]]. When the levels of [[Anti-diuretic Hormone|anti-diuretic hormone]] are low the [[water]] is not reabosrbed re-absorbed and is passed down the [[ureter]]s to the [[bladder]].
