==Overview==
The [[Urinary System Overview - Anatomy & Physiology#Upper Urinary Tract|kidney]] synthesises and secretes various products, including [[Hormones - Anatomy & Physiology|hormones]] and enzymes which have a vital role within the body.

|'''Renin'''
This enzyme forms a vital part of the [[Renin-Angiotensin-Aldosterone System (RAAS) - Anatomy & Physiology|Renin-Angiotensin-Aldosterone System]], a complex system of hormones and enzymes which act to raise blood pressure when stimulated by hypotension.

Renin is the enzyme for the creation of the hormone ''angiotensin''.

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

==Renin==
A proteolytic enzyme synthesised in the kidney. Renin affects blood pressure indirectly and is 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 on [[Erythropoiesis#Regulation|regulatioon of erythropoiesis]].
==Vitamin D==
The [[Calcium#Active Vitamin D Synthesis|activation of vitamin D]] is regulated by the kidneys under the influence of another hormone, [[Calcium#Parathyroid Hormone (PTH)|PTH]].
