===Renin-Angiotensin-Aldosterone System (RAAS)===
The juxtaglomerular apparatus of the kidneys plays an important role in the control of blood volume and blood pressure via the [[Renin Angiotensin Aldosterone System|RAAS]]- renin is released from this area. The stimulus for renin release into the circulation includes;
The juxtaglomerular apparatus of the kidneys plays an important role in the control of blood volume and blood pressure via the [[Renin Angiotensin Aldosterone System|RAAS]] - [[Kidney Endocrine Function - Anatomy & Physiology#Renin|Renin]] is released from this area. The stimulus for renin release into the circulation includes;
*local baroreceptors in the afferent renal arteriole - a drop in renal blood flow stimulates renin release
*local baroreceptors in the afferent renal arteriole - a drop in renal blood flow stimulates renin release
*cardiac and arterial baroreceptors responsd to reduced local perfusion, initiating beta-1 mediated effects via innervation of the juxtaglomerular apparatus (JGA)
