==Key Stage 4==
===Meaning===
[[Osmoregulation]] is the process of keeping the [[concentration]] of [[water]] and [[salt]]s constant in an [[organism]].
===About Osmoregulation in Humans===
: [[Osmoregulation]] in [[human]]s is controlled by the [[kidney]]s.
: There are several ways [[human]]s can lose [[water]] so the [[kidney]]s must perform [[osmoregulation]] to ensure that too much [[water]] is not lost. The body loses [[water]] every time we [[exhale]] as some [[water vapour]] is lost from the [[lung]]s. The body also loses [[water]] when we [[sweat]].
: [[Water]] is removed from the [[blood]] and passed into [[Kidney Tubule|tubules]] in the [[kidney]]s. The [[water]] is then selectively reabsorbed into the [[blood]] depending on how much [[water]] is needed.
: [[Osmoregulation]] in the [[kidney]]s is affected by [[Anti-diuretic Hormone|anti-diuretic hormone]].
: When there is not enough [[water]] in the [[blood]] the [[Pituitary Gland|pituitary gland]] [[secrete]]s [[Anti-diuretic Hormone|anti-diuretic hormone]] which causes the [[Kidney Tubule|tubules]] allow [[water]] back into the [[blood]].
: When there is too much [[water]] in the [[blood]] the [[Pituitary Gland|pituitary gland]] stops [[secrete|secreting]] [[Anti-diuretic Hormone|anti-diuretic hormone]] which causes the [[Kidney Tubule|tubules]] stop allowing [[water]] back into the [[blood]].
