\n\n\n\nExplanation:<\/h3>\n\n\n\n
\n
Renin is secreted by the juxtaglomerular cells<\/strong> of the kidneys in response to:<\/li>\n<\/ol>\n\n\n\n\n
\n
Once released into the bloodstream, renin acts on a protein called angiotensinogen<\/strong>, which is produced and released by the liver. Renin cleaves angiotensinogen<\/strong> to form angiotensin I<\/strong>, which is an inactive precursor.<\/li>\n\n\n\n
Angiotensin I is then converted into angiotensin II<\/strong> by the enzyme angiotensin-converting enzyme (ACE)<\/strong>, primarily in the lungs.<\/li>\n\n\n\n
Angiotensin II is a potent vasoconstrictor<\/strong>\u2014it narrows blood vessels and raises blood pressure. It also stimulates the release of aldosterone<\/strong> from the adrenal glands, which promotes sodium and water reabsorption in the kidneys, further increasing blood volume and pressure.<\/li>\n<\/ol>\n\n\n\n
