Urinary System
primary function is to regulate the volume and composition of fluids in the body and remove waste products from the blood.
rlie just above the waist on either side of the vertebral column, behind the posterior wall of the abdomen.  Embedded in adipose tissue as protection.  Play an important role in regulating blood pressure.
help regulate blood composition and urine formation, located inside the kidneys, each kidney contains over 1 million of these blood processing units.
Renal Artery
takes blood into the kidney, branches into arterioles, and then into the nephrons.
Renal vein
takes blood out of the kidneys that has been processed by the nephrons.
Renal pelvis
enlarged funnel-shaped extension of the urteter that receives waste material from the nephrons and takes waste out through the ureter.
primary sex organs for both men and women.
paired oval glands that descend into the scrotum, contain specialized structures that are responsible for producing the gametes (sperm).
Saclike structure holding testes.
Vas deferens
sperm transporting duct, long tube for transporting sperm.
Ejaculatory ducts
Duct that ejaculates sperm.
Prostate Gland
Located next to the ejaculatory ducts.
exerternal genital organ in males. Used for reproduction and urination.

kidney, tumor of the kidney
ren/o, renal
kidney, pertaining to the kidney
pyel/o, pyel/o/lith/o/tomy

above, excessive,  located above the kidneys.
-kal-, hyper/kal/emia
potassium, excessive potassium in the blood.
-azot-, hypo/azot/uria
nitrogenous compounds,  excretion of abnormally small quantities of nitrogenous compounds.
-uria, an/uria
urine,  absence of urine formation.
orcho/o, orch/itis
testes, inflammation of one or both of the testes.
orchi/o, orchi/o/pexy
testes, surgical fixation of an undescended testicle by implanting it into the scrotum

testes, excision of one or more testicles.
test/o, test/is
testes, one pair of male gonads that produce sperm and testosterone.
prostat/o,  prostat/o/megaly
prostate gland, enlargement of the prostate.
spermat/o, spermat/o/lysis
sperm, destruction of sperm
sperm/o, oligo/sperm/ia
sperm, a temp or permanent deficiency in the number of spermatozoa in the semen.
vas/o, vas/ectomy
vessel, vas deferens, duct,  procedure for male sterilization involving removal of a part of the vas deferens.
circum-, circum/cision
around,  removal of the foreskin of the penis.
para-, para/phim/osis
near, beside, beyond,  abnormal condition characterized by inability to replace foreskin in normal condition after retraction behing the glans penis (muzzle-phim).
complete suppression of urinary secretion by the kidneys.
abnormal secretion of large amounts of urine.
painful or difficult urination
end-stage renal disease
final phase of kidney disease process (ESRD)
Involuntary discharge of urine after the age by which bladder should have been established. (Bedwetting at night)
blood in the urine.
distention of the renal pelvis and calyces of a kidney caused by a urinary tract obstruction.  The pressure, which is due to accumulated urine, may eventually interrupt kidney function.
Condition characterized by the presence of Kidney stones.  (Renal Calculi).
excessive urination at night, genally due to a large prostate.
Diminished or scanty urination in relation to fluid intake.  
excessive thirst.  A sign of diabetes.
a bacterial infection of the renal pelvis and renal medulla of one or both kidneys.  Bladder infection backed up into the kidneys, very serious condition.
the presence of white blood cells in the urine.  Pus in urine.
Renal Hypertension
high blood pressure resulting from a kidney disease.
Urinary incontinence
Intermittent or complete absence of ability to control the release of urine from the bladder.
Benign prostatic hyperplastia 
A nonmalignant enlargement of the prostate due to excessive growth of prostatic tissue. (BPH) 
Transurethral Prostatectomy
To control BPH that isn't controllable with medications.  (TURP)

Prostatic cancer
A malignant neoplasm of the prostate tissue, creating pressure on the upper part of the urethra.
insertion of a catheter (hollow flexible tube) into a body cavity or organ to instill a substance or remove a fluid.
Visual examination of the urinary bladder by inserting a cystoscope into the urethra.
Surgical removal of the foreskin or the prepuce of the penis.

Removal of all or a segment of the vas deferens.
Process of diffusing blood across semipermeable membrane to remove toxic materials to maintain fluid, electrolyte, and acid-base balances in cases of impaired kidney function or absence of the kidneys.
