Diuretics antamony Flashcards
(24 cards)
what is the function of diuretics?
decrease cardiac workload–> decrease stroke volume and lower bp
who uses diuretics mainly?
HF (respiratory complication) , pt with edema, and
what is the positioning of the kidneys
bilaterally retroperitoneal
outer area of kidney?
cortex
inner part of kidney?
medulla
what will we see inside cortex?
glomeruli (MOST are there), tubules
medulla has mostly?
collecting ducts
what is the basic unit of the kidney?
nephron
what is a glomerulus>
cluster of capillaries (where filtering of blood occurs
afferent arterioles are?
blood vessels that approach the glomerulus
efferent arterioles are?
blood vessels that exit glomerulus
bowmans capsule surrounds?
glomerulus
what is the pathway of the nephron and duiretic
glomerulus–> bowmans capsule—>proximal tubule —> loop of henle (descending and ascending)–> distal tubule–> collecting duct–> renal pelvis-utuers–> bladder–> urthera
what hormone controls the distal tubule
aldosterone
what hormone controls the collecting duct?
ADH
renin is apart of?
afferent blood vessels with macula densa cells
what tells us how fast the kidney is going?
GFR (glomerular filtration rate)
normal GFR?
60%
what can u do to bring up GFR?
drink more water, avoid meds that affect kidneys
proximal convoluted tubule reabsorbs how much?
60-70%(that kidney filtered out) of Na and H2O
urine comes from?
blood
Loop of henle reabsorbs how much?
20-25% of Na+
distal convoluted tubule reabsorbs how much?
5-10% of Na
function of diuretic drug?
inhibit absorption of Na+ and H2O
