Renin Angiotensin Aldosterone Mechanism Concept Map
Directly stimulates the pituitary to release triggers vasoconstriction which increases catalyzes the conversion of angiotensinogen to angiotensin i renin is converted by ace in when low triggers lung capillaries into kidney granular cells of the kidneys to release angiotensin ll blood volume and directly stimulates the adrenal cortex to release directly stimulates tubular reabsorption which increases catalyzes the conversion of angiotensinogen to directly stimulates the adrenal cortex to.
Renin angiotensin aldosterone mechanism concept map. List functions of angiotensin ii 2. Baroreceptors will decrease firing leading to increased sympathetic activity causing vasoconstriction decrease in gfr and increased sodium reabsorption. Secretion of aldosterone causes sodium and water retention 2. Renin from juxtaglomerular cells stimulates angiotensinogen.
What are the transporters on the membranes of the proximal tubule for sodium. The renin angiotensin aldosterone system is one of the most complex and important systems in controlling the blood pressure in your body. With the help of angiotensin converting enzyme from the lungs 5. Using no more than 13 propositions describe the role of the renin angiotensin aldosterone mechanism in regulating blood volume and pressure.
Renin angiotensin aldosterone system 1. What is the cardiovascular baroreceptor response to a drop in blood pressure. How does this relate to sodium reabsorption. As we go over this system you ll also learn about the.
Renin is synthesized in the kidneys as an inactive form and released into circulation in response to low levels of intratubular sodium hypotension in the afferent arterioles of renal. Anatomical diagram of ras 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 angiotensin aldosterone system is the key regulator and the juxtaglomerular apparatus is the important nephron structure. Definition of key terms renin angiotensin angiotensin converting enzyme ace 3.
