|Also known as ''Active Vitamin D3'', or ''1-25-Dihydroxyvitamin D3'', Calcitriol is vital for [[Calcium Homeostasis - Anatomy & Physiology|Calcium Homeostasis]], and acts to raise plasma calcium levels. Within the kidney, vitamin D from dietary sources or the skin is 'activated' by hydroxylation.

Kidneys are responsible for the production and release of two hormones [[Erythropoiesis#Regulation|Erythropoietin]] and [[Reabsorption and Secretion Along the Distal Tubule and Collecting Duct - Anatomy & Physiology#Renin|Renin]]. Both of these hormones are from the [[Reabsorption and Secretion Along the Distal Tubule and Collecting Duct - Anatomy & Physiology#Juxtaglomerular Cells|Juxtaglomerular Cells]]. It is also responsible for the regulation of the [[Calcium Homeostasis - Anatomy & Physiology #Active Vitamin D Synthesis |activation of vitamin D]]
==Renin==
* A proteolytic enzyme synthesised in the kidney
* Renin affects blood pressure indirectly
* Part of the first stage of the [[Renin Angiotensin Aldosterone System| renin-angiotensin-aldosterone-system]]
** Its effects are through its activation of this system by the conversion of angiotensinogen to angiotensin 1
==Erythropoietin==
Erythropoietin is a glycoprotein hormone produced in the kidneys in adult life. Its function is beyond the scope of this section and more information can be found [[Erythropoiesis#Regulation|here]]
==Vitamin D==
The [[Calcium Homeostasis - Anatomy & Physiology#Active Vitamin D Synthesis|activation of vitamin D]] is regulated by the kidneys under the influence of another hormone [[Calcium Homeostasis - Anatomy & Physiology#Parathyroid Hormone (PTH)|PTH]]
