|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]]
