Descriptor sistema renina-angiotensina
Entry term(s) sistema renina-angiotensina-aldosterona
Scope note: Sistema regulador de la PRESIÓN ARTERIAL en el que interactúan componentes tales como: RENINA, ANGIOTENSINA, ENZIMA CONVERTIDORA DE ANGIOTENSINA, ANGIOTENSINA I, ANGIOTENSINA II, y angiotensinasa. La renina, una enzima producida en el riñón, actúa sobre el angiotensinógeno, una globulina alfa-2 producida en el hígado, para formar ANGIOTENSINA I. La enzima convertidora de angiotensina, contenida en el pulmón, actúa sobre la angiotensina I plasmática, convirtiéndola en ANGIOTENSINA II, que es un agente vasoconstrictor extremadamente potente. La angiotensina II causa contracción del MUSCULO LISO VASCULAR arteriolar y renal, lo que provoca una retención de sal y agua por parte del RIÑÓN y un incremento de la presión arterial. Además, la angiotensina II estimula la liberación de ALDOSTERONA en la CORTEZA SUPRARRENAL que, a su vez, incrementa la retención de sal y agua en el riñón. La enzima convertidora de angiotensina inactiva a la BRADIQUININA, un poderoso vasodilatador y componente del SISTEMA CALICREÍNA-CININA.

Scope note: A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.
