7 Urinary System Flashcards
albuminuria
Abnormal condition of protein in the urine
anuria
abnormal condition of no urine production
dysuria
painful urination
glycosuria
abnormal condition of glucose in the urine
hematuria
abnormal condition of blood in the urine
nephrolithiasis
abnormal condition of stones in the kidney
renal failure
Condition in which the kidneys stop functioning and do not produce urine
uremia
Condition of high levels of urea in blood
Blood Urea Nitrogen (BUN)
Measures the amount of urea (nitrogenous waste) in the blood
Creatinine
Used to evaluate renal function
Urography
X-ray imaging of the urinary tract after injection of contrast material
Cystoscopy
Visual examination of the urinary bladder with a cystoscope
Kidneys, Ureters, Bladder (KUB)
X-ray image of the kidneys and urinary tract without the use of contrast
Retrograde Pyelogram (RP)
Contrast material injected via catheter into the urethra and bladder and x-rays are taken
Voiding Cystourethrogram (VCUG)
X-rays of the bladder and urethra are taken after the bladder is filled with contrast material and while the patient is voiding urine
ARF
Acute Renal Failure
BUN
Blood Urea Nitrogen
CAPD
Continuous ambulatory peritoneal dialysis
CKD
Chronic kidney disease
CRF
Chronic renal failure
HD
Hemodialysis
KUB
Kidneys, ureters, bladder
RP
Retrograde pyelogram
UA
Urinalysis
UTI
Urinary tract infection
Nitrogenous waste excreted in urine.
This is a product of muscle metabolism.
Creatinine
Chemical element that carries an electrical charge when dissolved in water.
These are necessary for functioning of muscles and nerves. The kidneys have a role in maintaining proper balance of these chemical elements as well as water.
electrolytes
One of two bean shaped organs on either side of the backbone in the lumbar region. It filters nitrogenous waste from the bloodstream to form urine.
Kidney
Functional unit of the kidney. It is a combinations of glomerulus and renal tubule where filtration, reabsorption, and secretion take place in the kidney
nephron
Tiny ball of capillaries in the kidney
Glomerulus
Outer region of an organ
Cortex
Tube for injecting or removing fluids.
Catheter
Inner region of an organ
Medulla
Electrolyte regulated by the kidney so that a proper concentration is maintained within the blood. This electrolyte is essential for allowing muscle contraction and conduction of nervous impulses.
Potassium (K+)
Blood vessel that carries blood to the kidney
Renal artery
Microscopic tube in the kidney where urine if formed after filtration.
Renal tubule
Electrolyte regulated in the blood and urine by the kidneys. It is needed for the proper transmission of nerve impulses, heart activity and other metabolic functions.
Sodium (Na+)
Major nitrogenous waste excreted in urine
Urea
One of the two tubes leading from the kidneys to the urinary bladder.
Ureter
Uric acid
Nitrogenous waste excreted in the urine
Hollow, muscular sac that holds and stores urine.
Urinary bladder
Urination
voiding
Process of expelling urine; also called micturition
cyst/o
urinary bladder
glomerul/o
glomerulus
nephr/o
kidney
pyel/o
renal pelvis
ren/o
kidney
ureter/o
ureter
urethr/o
urethra
vesic/o
urinary bladder
creatinine clearance
Measurement of the rate at which creatinine is cleared from the blood by the kidney
Process of separating nitrogenous waste materials from the blood.
This is used to treat renal failure.
Dialysis
arteriole
Small artery
calciferol
active form of vitamin D, secreted by the kidney
Calyx (or calix)
plural: calyces or calices
Cup-like collecting region of the renal pelvis.
Erythropoietin (EPO)
Hormone secreted by the kidney to stimulate the production of red blood cells
filtration
Process whereby some substances but not all, pass through a filter
Glomerular capsule
Enclosing structure surrounding each glomerulus. Also know as Bowman capsule and collects the material that is filtered from the blood through the walls of the glomerulus.
Glomerulus
Tiny ball of capillaries in the kidney.
Hilum
Depression in the kidney where blood vessels and nerves enter and leave.
Medulla
Inner region of an organ
Nephron
Functional unit of the kidney. It is the combination of glomerulus and renal tubule where filtration, reabsorption, and secretion take place in the kidney. Each nephron is capable of forming urine by itself. There are about 1 million nephrons in a kidney.
Nitrogenous waste
Substances containing nitrogen and excreted in the urine. Examples are urea, uric acid, and creatinine.
Reabsorption
Process whereby renal tubules return materials necessary to the body back into the bloodstream.
Renal artery
Blood vessel that carries blood to the kidney
Renal pelvis
Central collection region in the kidney
Renal tubule
Microscopic tube in the kidney where urine is formed after filtration
Renal vein
Blood vessel that carries blood away from the kidney and toward the heart.
Renin
Enzymes secreted by the kidney. It raises blood pressure by influencing vasoconstriction (narrowing of blood vessels)
Trigone
Triangular are in the urinary bladder
Urea
Major nitrogenous waste excreted in the urine
Ureter
One of the two tubes leading from the kidneys to the bladder
Urethra
Tube leading from the urinary bladder to the outside of the body.
Urinary bladder
Hollow, muscular sac that holds and stores urine.
Urination (voiding)
Process of expelling urine, also called micturition
bacteri/o

thirst
kal/i

ket/o, keton/o

Glomerulonephritis
Inflammation of the glomeruli within the kidney
Nephrotic syndrome
Group of clinical signs and symptoms caused by excessive protein loss in the urine
Pyelonephritis
Inflammation of the lining of the renal pelvis and renal parenchyma. (The parenchyma of an organ is its essential and distinctive tissue. Nephrons make up the renal parenchyma)
Renal failure
Decrease in excretion of wastes results from impaired filtration function.
