 The role of the RAAS is the long‐term management of blood volume and arteriolar tone.

 This is achieved by increasing reabsorption of sodium and water, and increasing vascular tone.

 In contrast, the baroreceptor reflex manages smaller and short‐term changes.Figure 5.2 Schematic of the renin angiotensin‐aldosterone‐system (RAAS).

 The RAAS has three main components:Renin.Angiotensin II.Aldosterone.

 A decrease in renal blood pressure results in these components acting to increase arterial pressure or decrease salt delivery to the distal convoluted tubule.

 These mechanisms allow for prolonged increases in systemic blood pressure.
