The Renin angiotensin system is a hormone system that regulates blood pressure and blood volume. This happens when Renin is produced and released by the kidneys in response to decreased blood pressure. Renin then is converted from angiotensinogen to angiotensin I and ACE converts angiotensin I to angiotensin II. Angiotensin I is converted into angiotensin II by the angiotensin-converting enzyme that is located in the lungs.
Angiotensin II is a vasoconstrictor that helps increase blood pressure by constricting the blood vessels and cause the release of aldosterone. Aldosterone is responsible for regulating salt and water in the body.What do you think could happen if that system was not in place or was malfunctioning?If this system was not in place or malfunctioning blood pressure would increase and there would be no way to keep blood pressure at a therapeutic level. Hypertension can strain the heart, damage blood vessels, and increase the risk of heart attack, stroke, kidney problems, and even death.
