Detailed explanation-1: -Typically, RAAS is activated when there is a drop in blood pressure (reduced blood volume) to increase water and electrolyte reabsorption in the kidney; which compensates for the drop in blood volume, thus increasing blood pressure.
Detailed explanation-2: -It acts directly on the nephrons, decreasing glomerular filtration rate. Thus, via the RAAS, the kidneys control blood pressure and volume directly.
Detailed explanation-3: -Myocardial systolic dysfunction Activation of the renin-angiotensin-aldosterone system (RAAS) also results in vasoconstriction (angiotensin) and an increase in blood volume, with retention of salt and water (aldosterone).
Detailed explanation-4: -Hint: The RAAS functions to elevate blood volume and arterial tone in a prolonged manner. It does this by increasing sodium reabsorption, water reabsorption, and vascular tone.
