urinary sys Flashcards
aldosterone
a horomone that the adrenal glands release to help regulate blood pressure by managing sodium and potassium
atrial natriutetic peptide (ANP)
a cardiac hormone regulating salt water balance and blood pressure through vasodilation
bladder
a hollow organ in the lower abdomen that stores urine
bowman’s capsule
a part of the nephron that forms the cup-like sack that surrounds the glomerulus
calculi
a stone; usually composed of mineral salts
calyx (calyces)
a funnel-shaped structure that acts as a passageway of urine from the papillary ducts aka the renal pelvis
collecting ducts
a segment of the nephron that returns water from the filtrate to the bloodstream.
cortical nephron
a tiny component of the kidney that only enters the outer renal medulla by a brief Henle loop.
what does the root calyc mean
to cover/conceal
what does the suffix sterone mean
steroid hormones.
distal tubule
the nephron segment between the mecula densa region and the cortical collecting tube.
diuretic
medicines that help to reduce fluid buildup in the body.
enuresis
involuntary urination.
en root means what
with or inside
glomerular filtration
the flow of plasma from the glomerulus into the bowman’s space over a period of time.
glomerular filtration rate
represents the flow of plasma from the glomerulus over a specific period of time.
glomerulus
a cluster of small blood vessels around the end of the kidney tubule.
glomer root means what
ball shaped
hematuria
blood in the urine
hem
blood
uria
urine
incontinence
lack of control over urination or defecation.
juxtamedullary nephron
long loops of Henle that extend deep into the inner medulla.
juxta
near, nearby, or close
kidney
a pair of organs located to right and left sides of the abdomen
micturition
process of emptying urine from the bladder
nephron
each of the functional units in the kidney, consisting of a glomerulus and its associated tubule, through which the glomerular filtrate passes before emerging as urine.
- Most reabsorption of substances from the glomerular filtrate occurs in the:
proximal convoluted tubule
- Under normal circumstances, the kidneys produce about _____ liters of glomerular filtrate per day.
180
- As the renal artery approaches the kidney, it branches to supply the renal glomeruli. Place the following in the correct sequence starting from the renal artery. - NOT ON THE QUIZ
interlobular artery,interlobar artery,arcuate artery,afferent arteriole
- ADH is produced in the:
hypothalamus
- When ADH levels in the blood are high, the collecting ducts are:
very permeable to sodium and chloride ions - sodium (and water) moves back into the body
does the renal cortex contains A. renal pyramids B. papillae C. calyces
NONE
the A. proximal convoluted tubule
has active transport and passive flow of what
Active transport of sodium; water follows passively
D. ascending limb of the nephron loop has active transport and impermiable flow of what
Active transport of sodium; impermeable to wate
B. descending limb of the nephron loop has passive flow of what
water
