Raa pathway - Study guides, Class notes & Summaries

Describe pathway of RAA system. - Kidney secretes renin in response to low blood volume → renin travels to liver & triggers production of angiotensin I → angiotensin I travels to lungs & converts to angiotensin II → angiotensin II travels to adrenal glands & stimulates production of aldosterone What are the effects of aldosterone release on fluid & electrolyte balance? - - increases renal retention of Na+ - increases renal excretion of K+ - increases water retention - increases bloo...

MEDICAL/AMLS FINAL REVIEW QUESTIONS AND ANSWERS, 100% ACCURATE/ Headache, nuchal rigidity, fever/chills and photophobia is a classic sign of: - -Meningitis Patients who have headache and fever should be assessed for: (which sign(s)?) - -Kernig's (pain when extension of knee at sitting position; 'K' in Kernigs and knee) and Brudzinsky's signs (involuntary flexing of legs when flexing neck). Positive tests would indicate meningitis. Fluid shifting in lungs is: - -ARDS (Acute Respirator...

ADH - -increases permeability to water in cells of the distal tubule and collecting duct causing higher water reabsorption -increases aquaporin, water channels, content in the apical membrane -increases blood pressure and volume ANP - -decreases Na and water reabsorption -inhibits aldosterone and ADH release Buffering of H+ in the Urine - free H+ can be reabsorbed through a pump therefore we want it to bind to something Colloid Osmotic Pressure (COP) - -osmolarity of plasma proteins -25...

Systolic - Blood pressure in the arteries during contraction of the ventricles. Diastolic - occurs when the ventricles are relaxed; the lowest pressure against the walls of an artery Systolic BP - peak pressure during cardiac systole - Reflects amount of blood (Stroke Vol.) -ejected w/ each beat & compliance of the aorta and large arteries Diastolic BP - lowest pressure attained in arteries during diastole -Reflects closure of the aortic valve, energy stored in the elastic fibers of larg...
