→About the Kidneys
===About the Kidneys===
: The [[kidney]]s are responsible for [[osmoregulation]] as well as the removal of [[urea]] from the [[blood]].
: As [[blood]] passes through the [[kidney]]s [[water]], [[urea]], [[glucose]] and [[salt]]s [[Diffusion|diffuse]] from [[capillaries]] into the kidney tubulesat in a structure called a [[nephron]]. [[Glucose]] is completely reabsorbed into the [[blood]] while [[water]] is selectively reabsorbed depending on the [[water]] [[concentration]] in the [[blood]].
: The selective 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 re-absorbed and is passed down the [[ureter]]s to the [[bladder]].
