Summary Introduction
To review:
The basic steps of the renin–angiotensin–aldosterone system.
Introduction:
RAAS (renin–angiotensin–aldosterone system) pervasively impacts the tubular reabsorption within the nephron as well as collecting system for influencing blood volume and electrolyte balance. RAAS represents a system thatmaintains systemic blood pressure and preserves the GFR (glomerular filtration rate).
