RAAS Basics
This long name of RAAS regulates long-term blood pressure
What is the Renin-Angiotensin-Aldosterone System?
This bean-ish looking organ releases renin and renal means this filter organ
What are the kidneys?
This hormone causes sodium & water retention
What is aldosterone?
Vasoconstriction has this effect on BP
What is increases blood pressure?
These drugs "go against" high blood pressure
What are antihypertensives?
This trigger activates RAAS
What is a drop in blood pressure?
This substance released by the liver starts the the process of blood vessel contraction and relaxation
What is angiotensinogen?
This adrenaline-producing gland releases aldosterone, to retain BV volume
What are the adrenal glands?
Na⁺ (sodium) reabsorption has this effect on BP
What is increased blood volume?
With one heart, these betas "prevent" the heart from overreacting
What are beta (1)-blockers?
This elevating action is the primary goal of RAAS
What is raising blood pressure?
Renin + angiotensinogen form this peptide hormone
What is angiotensin I?
Anti-diuretic hormone (ADH) presses the BV and is aka this vessel squeezer
What is vasopressin?
+ blood volume = increased BP, causing these 2 side effects
What are increased thirst (polydipsia) and decreased urine output (oliguria)?
If the heart is sad & slow, you beta inject these
What are beta-1 agonists?
RAAS helps correct this depressing condition
What is hypotension?
This lung-produced enzyme converts Ang I → Ang II
What is ACE--angiotensin converting enzyme?
Diuretics rid fluids to reduce BP. Antidiuretics do this to increase BP
What is retain fluids?
When sodium is retained, this vital fluid increases
What is blood [volume]?
If the BP is lagging, pick up the pace with ACE from this hollow organ
What are the lungs?
The medical name for increased blood vessel resistance aka hypertension
What is increased vascular resistance?
RAAS puts the squeeze on to create this desired action
What is vasoconstriction?
This "low" thalamus part of the brain controls most of RAAS--including increasing thirst
What is the hypothalamus?
If RAAS doesn't effectively increase BP, the patient likely needs this
What is medication [beta-agonists]?
Renal means this __, which also produces this__ -- the beginning of RAAS (2 answers)
What are the kidneys / renin?
