Renin, which is released primarily by the kidneys, stimulates the formation of angiotensin in blood and tissues, which in turn stimulates the release of aldosterone from the adrenal cortex. Renin is a proteolytic enzyme that is released into the circulation by the kidneys. Its release is stimulated by:
The components discussed in the RAAS have included renin, angiotensinogen, angiotensin I, angiotensin II, and ACE. To summarize, RAAS activation leads to renin release from the kidneys. Renin cleaves angiotensinogen, which is released by the liver, to form angiotensin I.
Thyroid hormone affects renin release through a mechanism independent of the ouabain-sensitive sodium pump and protein synthesis, since ouabain and cycloheximide did not modify renin release or production. The results of this study suggest that thyroid hormone plays a role in renin release from the juxtaglomerular cells. PMID: 616172 Antidiurectic Hormone. As previously discussed, antidiuretic hormone or ADH (also called vasopressin), as the name suggests, helps the body conserve water when body fluid volume, especially that of blood, is low.
Angiotensin II causes the adrenal glands to secrete the hormone aldosterone which acts on the kidneys to reduce the loss of sodium in the urine. Plasma renin activity (PRA), also called plasma renin assay, may be used to screen for high blood pressure (hypertension) of kidney origin, and may help plan treatment of essential hypertension, a genetic disease often aggravated by excess sodium intake. The kidneys also produce prostaglandins, hormone-like substances, made from lipid (fat). The substances are one way in which the production of renin is stimulated. Renin is an enzyme, also produced by the kidneys, that plays an important role in the renin– angiotensin – aldosterone hormonal system, which helps to control blood pressure. Renin is released in response to decreased blood volume or pressure and is part of the renin-angiotensin-aldosterone system that leads to the release of aldosterone. Aldosterone then causes the retention of Na + and water, raising blood volume.

Renin omvandlar angiotensinogen i blodplasma till angiotensin I. Angiotensin I omvandlas i sin tur av enzymet ACE (angiotensinkonverterande enzym) i lungornas kapillärer till slutprodukten angiotensin II. Renin is an enzyme that is produced by the granular cells of the afferent arteriole at the JGA. It enzymatically converts angiotensinogen (made by the liver, freely circulating) into angiotensin I. Its release is stimulated by prostaglandins and NO from the JGA in response to decreased extracellular fluid volume. 2021-04-11 · Renin is an enzyme secreted into the blood from specialized cells that encircle the arterioles at the entrance to the glomeruli of the kidneys (the renal capillary networks that are the filtration units of the kidney). The renin-secreting cells, which compose the juxtaglomerular apparatus, are sensitive to changes in blood flow and blood pressure. Structural analysis suggests that renin is released by compound exocytosis Dominik Steppan1, Anita Zu¨gner1, Reinhard Rachel2 and Armin Kurtz1 1Physiologisches Institut der Universita ¨t Regensburg, Regensburg, Germany and 2Anatomisches Institut der Universitat Regensburg, Renin is an enzyme, also produced by the kidneys, that plays an important role in the renin–angiotensin–aldosterone hormonal system, which helps to control blood pressure.

Renin is a proteolytic enzyme that is released into the circulation by the kidneys. Its release is stimulated by:
Its release is usually stimulated by decreases in blood pressure, and so the preservation of adequate blood pressure is its primary role.

Renin catalyses the release of angiotensin I from a blood globulin angiotensinogen, and this, in turn, is converted to angiotensin II by a converting enzyme found in the lung. Angiotensin II causes the adrenal glands to secrete the hormone aldosterone which acts on the kidneys to reduce the loss of sodium in the urine. Plasma renin activity (PRA), also called plasma renin assay, may be used to screen for high blood pressure (hypertension) of kidney origin, and may help plan treatment of essential hypertension, a genetic disease often aggravated by excess sodium intake.
