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.

What then does ANP try to achieve?arrow_forwardPlease help me with these questions, more than one answer may be correct for each:1) Which of the following statements are true about the renin-angiotensin-aldosterone axis? A) Angiotensin II stimulates production of aldosterone, which increases sodium reabsorption B) Renin converts angiotensinogen to angotensin I C) Angiotensin II stimulates production of vasopressin, which increases aquaporins in the collecting duct D) Vasopressin decreases thirst E) Renin lowers GFR 2) The purpose of excretion is to A) maintain internal pH B) remove harmful substances C) maintain plasma volume D) maintain osmotic balance E) maintain internal solute concentrationarrow_forward
- Renin is secreted in response to hypovolemia or to an increase in the osmolality of the blood. Provide three possible mechanisms by which these conditions may stimulate rennin secretion. What are the consequences of increased rennin secretion that lead to increased aldosterone secretion? Present this sequence of events.

- Spironolactone is a widely prescribed diuretic ("water pill" - make you pee) which works by acting as an antagonist to aldosterone thus blocking its actions.
