Chapter 24.4, Problem 8QC
Summary Introduction
To review:
The basic steps of the renin-angiotensin-aldosterone system.
Introduction:
RAAS (renin-angiotensin-aldosterone system) represents a system which maintains systemic blood pressure and preserves the GFR (glomerular filtration rate). It pervasively impacts the tubular reabsorption within the nephron as well as collecting system for influencing blood volume and electrolyte balance.
