90 Cards in this Set

  • Front
  • Back
arteriole
small artery
Bowman capsule
cup-shaped capsule surrounding each glomerulus
calyx or calix
cup-like region of the renal pelvis
catheter
tube for injecting or removing fluids
cortex
outer region; the renal cortex is the outer region of the kidney
creatinine
a waste product of muscle metabolism; nitrogenous waste excreted in urine
electrolyte
a chemical that carries an electrical charge in a solution. examples are potassium (K+) and sodium (Na+)
erythropoietin (EPO)
a hormone secreted by the kidney to stimulate the production of red blood cells
filtration
Passive process whereby some substances, but not all, pass through a filter or other material.

Blood pressure forces materials through the filter.

About 180 quarts of fluid are filtered from the blood daily, but the Kideny returns 98 to 99 percent of the water and salts.

Only about 1 and 1/2 quarts (1500 mL) of urine are excreted daily.
glomerulus
tiny ball of capillaries in cortex of kidney
hilum
depression or pit in that part of an organ where blood vessels and nerves enter and leave
kidney
one of two bean-shaped organs located behind the abdominal cavity on either side of the backbone in the lumbar region
meatus
opening or canal
medulla
inner region; the renal medulla is the inner region of the kidney
micturition
urination; the act of voiding
nephron
the combination of glomerulus and renal tubule where filtration, reabsorption, and secreation take place in the kidney
nitrogenous waste
substance containing nitrogen and excreted in urine
potassium (K+)
a salt (electrolyte) secreted from the bloodstream into the renal tubules to leave the body in urine
reabsorption
in this process, the renal tubules return materials necessary to the body back into the bloodstream
renal artery
carries blood to the kidney
renal pelvis
central collecting region in the kidney
renal tubule
microscopic tube in the kidney where urine is formed after filtration. In the renal tubeule, the composition of urine is altered by the processes of reabsorption and secretion
renal vein
carries blood away from the kidney
renin
an enzymatic hormone synthesized, stored, and secreted by the kidney; it raises blood pressure by influencing vasoconstriction (narrowing of blood vessels)
sodium (Na+)
a salt (electrolyte) regulated in the blood and urine by the kidneys
trigone
triangular area in the bladder where the ureters enter and the urthra exits
urea
major nitrogenous waste product excreted in urine
ureter
tube leading from each kidney to the bladder
urethra
tube leading from the bladder to the outside of the body
uric acid
nitrogenous waste excreted in the urine
urinary bladder
sac that holds urine
urination
process of expelling urine

AKA - micturition
voiding
emptying of urine from the urinary bladder; urination or micturition
cali/o
calic/o
calyx (calix)
cyst/o
urinary bladder
glomerul/o
glomerulus (collection of capillaries)
meat/o
meatus
neohr/o
kidney
pyel/o
renal pelvis
ren/o
kidney
trigon/o
trigone (region of the bladder)
urter/o
ureter
urethr/o
urethra
vesic/o
urinary bladder
albumin/o
albumin (a protein in the blood)
azot/o
nitrogen
bacteri/o
bacteria
dips/o
thirst
ket/o
keton/o
ketone bodies (ketoacids and acetone)
lith/o
stone
noct/i
night
olig/o
scanty
-poietin
substance that forms
py/o
pus
-tripsy
to crush
ur/o
urine (urea)
urin/o
urine
-uria
urination, urine condition
urinalysis tests
color
pH
protein
glucose
specific gravity
ketone bodies
sdiment
pus - pyuria
phenylketonuria (PKU)
bilirubin
glomerulonephritis
inflammation of the kideney glomerulus
interstitial nephritis
inflammation of the renal interstitium (connective tissue that lies b/t the renal tubules)
nephrolithiasis
kidney stones (renal calculi)
nephrotic syndrome
a group of symptoms caused by excessive protein loss in the urine (also called nephrosis)
polycystic kidneys
multiple fluid-filled saca (cysts) within and upon the kidney
pyelonephritis
inflammation of the renal pelvis and renal medulla
renal cell carcinoma (hypernephroma)
cancerous tumor of the kidney in adulthood
renal failure
failure of the kidney to excrete wastes and maintain its filtration function
renal hypertension
high blood pressure resulting from kidney disease
Wilms tumor
malignant tumor of the kidney occurring in childhood
bladder cancer
malignant tumor of the urinary bladder
diabetes insipidus
inadequate secretion or resistance of the kidney to the action of antidiuretic hormone (ADH)
diabetes mellitus
inadequate secretion or improper utilization of insulin
blood urea nitrogen (BUN)
measurement if urea levels in blood
creatinine clearance test
measures the rate at which creatinine is cleared from the blood by the kidney
CT scan
x-ray image with detailed cross-sectional views of organs and tissues
intravenous pyelogram (IVP)
x-ray image of the kidneys and uterus after injection of contrast into a vein
