WebMar 2, 2024 · Renin Angiotensin Aldosterone System Renin secretion with SGLT2is should be inhibited by increased Na + reabsorption by the MD or reduced SNS activity but should be stimulated by reduced BP and body fluid volumes. WebJan 3, 2015 · It causes an increase. If the blood flow to the kidney is decreased for any reason (for example, hemorrhage or dehydration), the kidney is one of the organs that will protect it's perfusion by causing an increase in BP through the renin-angiotensin-aldosterone system (RAAS).

Renin activates the renin–angiotensin system by using its endopeptidase activity to cleave the peptide bonds between leucine and valine residues in angiotensinogen, produced by the liver, to yield angiotensin I, which is further converted into angiotensin II by ACE, the angiotensin–converting enzyme primarily within the capillaries of the lungs.
