Renin Angiotensin Aldosterone System
The kidneys are crucial for long-term blood pressure regulation through the Renin-Angiotensin-Aldosterone System (RAAS).
What our notes say
- The kidneys are crucial for long-term blood pressure regulation through the Renin-Angiotensin-Aldosterone System (RAAS). (Renal Anatomy and Physiology)
- The fall in intravascular volume activates the renin-angiotensin-aldosterone system and ADH, so the kidney retains salt and water, and some primary sodium retention at the distal nephron (overfill) adds to the swelling. (Paediatrics and Child Health end of semester examination (MBPE): 10 January 2023)
- Controlled by renin-angiotensin-aldosterone system (RAAS) and serum potassium (Chemical Pathology Practice Examination)
- Volume conservation affects renin-angiotensin-aldosterone system (Medical Physiology Paper II MCQs)
- RAAS (Renin-Angiotensin-Aldosterone System) and Antagonism by ANP (5 marks) (CLINICAL BIOCHEMISTRY LAQs & SAQs)

Practice questions on Renin Angiotensin Aldosterone System
Stimulation of the renin-angiotensin-aldosterone system (RAAS) by the kidney primarily occurs in response to ---
- Decreased potassium levels in extracellular fluid
- Decreased atrial natriuretic peptide (ANP) secretion
- Decreased sodium delivery to the distal tubule
- Decreased antidiuretic hormone (ADH) secretion
Answer: C.
