Chapter 16 - Genitourinary System Flashcards
Bowman’s capsule (renal capsule)
cup-shaped end of renal tubule containing the glomerulus
calyx
cup-shaped part of the renal pelvis through which urine passes from the renal tubules
cortex
the outer layer of the kidney
glormerulus
collection of coiled intertwined capillaries located in the kidney cortex
kidneys
two organs on the posterior abdominal wall that filter the blood, excreting the end products of body metabolism in the form of urine, and regulating body mineral levels
medulla
the inner layer of the kidney
nephron
the structural and functional unit of the kidney, the parenchyma, numbering about a million and capable of forming urine
renal artery
one of two large arteries branching from the abdominal aorta that supplies blood to kidneys, adrenals, and ureters
renal pelvis
the funnel-shaped expansion of the upper end of the ureter
renal tubule
long, twisted tube leading from glomerulus to collecting tubules
renal vein
one of two large veins that carries blood from the kidneys to the inferior vena cava
ureter
the tubular structure through which urine passes from the kidney to the bladder
urethra
the passage through which urine is discharged from the bladder to the body exterior
urinary bladder
musculomembranous sac that stores urine, receiving it through the ureters and discharging it through the urethra
urinary meatus
opening of the urethra to the exterior
azoturia
excess urea (or other nitrogen compounds) in urine
calculus (renal) (pl., calculi)
kidney stone(s)
cystitis
inflammation of the urinary bladder
dialysis
the process of using an artificial kidney to filter waste materials from the body
“floating kidney”
a kidney not securely fixed in the usual location because of a birth defect or injury
glomerulonephritis
nephritis with inflammation of the capillary loops in the renal glomeruli
hydroneophrosis
distention of the renal pelvis with urine, caused by obstruction of the ureter
nephrolithiasis
a condition marked by the presence of renal calculi (stones)
nephroptosis
downward displace of a kidney
nephrorrhaphy
suture of the kidney
pyelitis
inflammation of the renal pelvis
renal failure
kidney fails to function normally, e.g., in excretion of body waste
renal transplant
transferring a kidney surgically from one person to another to replace a diseased structure
uremia
the retention of toxic body waste in blood
ureterostomy
creation of a new outlet for a ureter through the abdominal wall to the outside
urethritis
inflammation of the urethra
urinary tract infection (UTI)
an infection of the urinary tract
Wilms’ tumor
a malignant tumor of the kidney, usually affecting children under age 5
albuminuria
abnormal presence of serum albumin (protein) in the urine
anuria
no urine produced
bladder distention
full urinary bladder
blood chemistries
blood tests for kidney function, especially blood urea nitrogen (BUN) and creatinine
blood urea nitrogen (BUN)
the urea (in terms of nitrogen) concentration of serum or plasma; an important indicator of renal function
catheterization
passage of a catheter (tube) into the bladder to relieve bladder distention or for other purposes
Clinitest
popular test for urine glucose or other substances
continent
able to control urination (and/or defecation)
cystoscopy
visual examination of the urinary tract with a cytoscope
diuresis
increased excretion of urine
dysuria
painful or difficult urination
enuresis
uncontrolled urination while sleeping (bed-wetting)
frequency (urgency)
desire to urinate at short intervals, but discharging small amounts because of reduced bladder capacity
hematuria
the presence of blood in the urine
incontinent
inability to control urination (and/or defecation)
intravenous pyelogram (IVP)
a technique in radiology for examining the structures and evaluating the function of the urinary system
I & O
intake and output. the amount of fluids (usually) ingested and excreted in a given period of time, measured and charted
KUB
abbreviation for kidney, ureter, and bladder
micturate
urinate
nocturia, mycturia
excessive urination at night
oliguria
excreting a small amount of urine
pyuria
pus in the urine
retrograde pyelgram
a technique in radiology for examining the structures of the collecting system of the kidneys that is especially useful in locating an obstruction in the urinary tract
scan (renal)
an image produced after the patient is injected with a radioactive substance. it determines kidney shape and function
testape
special paper that changes color with dipped in urine
ultrasonography
imagining body structures but recording the echoes of high-frequency sound waves reflected by body tissues on a paper or other device
urinalysis (UA)
analysis of the urine, e.g., acidity, sugar level
urinary retention
inability to urinate for various reasons. body retains urine waste
vescio-
a combining form meaning “pertaining to the bladder”
void
to empty the bladder, urinate
Cowper’s glands
pea-sized glands that secrete lubricating fluid during intercourse. also called bulbourethral glands
glans penis
tip of the penis
penis
the organ of copulation
perineum
area between the scrotum and anus
prepuce
fold of skin covering the glans penis at birth; foreskin
