Renin ist ein Hormon und wird in der Niere gebildet. Es ist Bestandteil eines Systems, das den Blutdruck und das Flüssigkeitsvolumen im Kreislauf auf konstantem Niveau hält.

Renin höjer blodtrycket och blodflödet. Renin utsöndras när blodtrycket är så lågt att njurarna får för lite blod. Hormonet påverkar binjurebarken så att hormonet aldosteron bildas där. Det gör att blodtrycket och blodflödet ökar.

Also, there is a chance that it might be secreted by the placenta of the body. This enzyme is a very important part of the entire physiological system and it helps in the controlling of the blood pressure in the body. 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. When renin is released by the kidneys into the bloodstream, it converts angiotensinogen, a protein produced by the liver, into angiotensin I [ 5, 3 ]. Next, an enzyme produced in the lungs called angiotensin-converting enzyme (ACE) converts angiotensin I into angiotensin II. Renin converts angiotensinogen, which is produced in the liver, to the hormone angiotensin I. An enzyme known as ACE or angiotensin-converting enzyme found in the lungs metabolizes angiotensin I into angiotensin II. Angiotensin II causes blood vessels to constrict and blood pressure to increase.

Renin hormone

Tests for the proper function of renin are done when high blood pressure — hypertension — or hypotension are suspected. Plasma renin activity (PRA) test measurements are compared against levels of natural aldosterone hormone from the adrenal glands. The renin-angiotensin (RAA) system is a group of related hormones that act together to regulate blood pressure.It is called a system because each part influences the other parts and all are necessary for the whole to function correctly. The renin-angiotensin system or RAS regulates blood pressure and fluid balance in the body. When blood volume or sodium levels in the body are low, or blood potassium is high, cells in the kidney release the enzyme, renin.

The renin–angiotensin system (RAS), or renin–angiotensin–aldosterone system (RAAS), is a hormone system that regulates blood pressure and fluid and electrolyte balance, as well as systemic vascular resistance. Renin Enzyme and Renin Hormone Renin is one of the main enzymes that is secreted by our kidneys. Also, there is a chance that it might be secreted by the placenta of the body. This enzyme is a very important part of the entire physiological system and it helps in the controlling of the blood pressure in the body.

Plasma renin activity is a measure of the capacity of renin to generate angiotensin I (precursor of angiotensin II) . Another method is measuring plasma renin concentration (PRC, pg/ml).

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. Hormonal cues help the kidneys synchronize the osmotic needs of the body. Hormones like epinephrine, norepinephrine, renin-angiotensin, aldosterone, anti-diuretic hormone, and atrial natriuretic peptide help regulate the needs of the body as well as the communication between the different organ systems. However, renin gene expression is not influenced by thyroid hormone in the submandibular gland of male mice, since testosterone regulates renin gene expression more strongly than thyroid hormone . In mice, renin production and secretion are more dependent on the submandibular gland than the kidney ( 2 ). This video discusses the production of Renin from the kidney.
