WebThrough an additional step, angiotensin I is converted to angiotensin II. Angiotensin II causes blood vessels to narrow (constrict), which results in increased blood pressure. This molecule also stimulates production of the hormone aldosterone, which triggers the absorption of salt and water by the kidneys. WebAngiotensin II. Angiotensin II (ATII) is a very potent vasoconstrictor of the afferent and efferent arterioles, acting on two types of receptors, the AT1 and the AT 2 receptor …
WebApr 11, 2024 · April 11, 2024 by Brianna. Angiotensinogen is a protein hormone that is produced by the liver. It is a precursor to angiotensin I and angiotensin II, which are hormones that play a role in regulating blood pressure. Renin is an enzyme that is produced by the kidney. It is responsible for clipping off 10 amino acids from angiotensinogen to … WebAngiotensin II constricts arterioles throughout the body. In the kidney it has a greater affect on the efferent arterioles than on the afferent arterioles so it tends to maintain the GFR despite the decrease in renal blood flow due to constriction of the afferent arteriole.
WebDec 25, 2011 · The present study investigated the role of Ang II production in the plasma and kidney. Our results showed the concentration of Ang II in plasma had no significance during long-term oral administration JCP (p > 0.05), but the concentration of Ang II in kidney significantly decreased in JCP groups (p < 0.05). So, the kidney should be the target ... WebMay 13, 2024 · Angiotensin II is a potent vasoconstrictor that plays an immediate role in the regulation of blood pressure.
