Document Summary
Chapter 17: understand the stages of htn and blood pressures associated with each stage. Stage 2: over 160/100: understand the complications of persistent htn. Hypertensive nephropathy (kidney failure: understand the difference between rapid regulation and long term control of blood pressure, and the influence on the autonomic nervous system. Baroreceptors are in charge of moment-to-moment control of hr, renin-angiotensin- aldosterone system is in charge of long term regulation. Long term control of bp by controlling blood volume. Kidneys release renin due to reduced bp & sympathetic stimulation of beta 1 receptors. Moa: blocks ne & epinephrine to decrease foc = decreased bp, blocks renin release.

Ace inhibitor: stops angiotensin 1 from being converted to angiotensin 2: decreases angiotensin 2 = vasodilation, decreases aldosterone = decreased blood volume = decreased bp.
