Baroreceptor Reflex Flow Art: The baroreceptor reflex helps maintain blood pressure homeostasis by detecting changes in arterial stretch and triggering heart rate and vessel tone adjustments via the autonomic nervous system.
Renin Aldosterone Angiotensin: The renin-angiotensin-aldosterone system (RAAS) regulates blood pressure and fluid balance by promoting vasoconstriction and sodium retention in response to decreased blood volume or pressure.
The Enzyme Renin Converts The Pro Enzyme Angiotensin I: Renin, secreted by the kidneys, catalyzes the conversion of angiotensinogen to angiotensin I, which is further converted to angiotensin II, a vasoconstrictor that raises blood pressure.
Renin Angiotensin Aldosterone Pathway: This hormonal cascade begins with renin release from the kidneys, leading to the formation of angiotensin II, a potent vasoconstrictor, and the secretion of aldosterone, which promotes sodium and water retention.
