Web26 Jun 2024 · The secretion of renin is stimulated by the following three factors: When a fall in arterial blood pressure is detected by pressure sensitive receptors (baroreceptors) in the arterial vessels. Renin's primary function is therefore to eventually cause an increase in blood pressure, leading to restoration of perfusion pressure in the kidneys. Renin is secreted from juxtaglomerular kidney cells, which sense changes in renal perfusion pressure, via stretch receptors in the vascular walls.

WebIn the blood, renin acts on a protein known as angiotensinogen, resulting in the release of angiotensin I. Angiotensin I is cleaved by angiotensin-converting enzyme, splitting off two amino acids from the 10-amino-acid chain of angiotensin I, to form angiotensin II. Webrenin, enzyme secreted by the kidney (and also, possibly, by the placenta) that is part of a physiological system that regulates blood pressure. In the blood, renin acts on a protein …

WebA stimulus triggers renin secretion. Renin promotes the conversion of angiotensinogen (produced in the liver ) to angiotensin I (AT I) . AT I is turned into angiotensin II via angiotensin-converting enzyme (highest concentration in the lungs where it is produced by vascular endothelial cells). WebProrenin/renin secretion is under the control of Ang II through a negative feedback loop. Thus, the magnitude of compensatory prorenin/renin secretion appears dependent on the degree of RAAS activation through the Ang I–Ang II arm. Hence, Ang II generation blockade with ACE-inhibitors and complete blockade of renin activity with DRIs increase ...

WebWhat is abnormal renin secretion? A hypotensive response, or lack of it, to angiotensin-converting enzyme inhibitor is similarly informative.
