Urinary Elimination Flashcards
process of removing waste
products from blood
Urinary elimination
functional unit of kidney
Nephrons
represents flow of plasma from glomerulus into Bowman’s
space. Chief measure of kidney function
Glomerular filtration rate (GFR)
two small tubes that transport urine into the bladder
Ureters
it filters the blood by removing waste and excess fluid in the body
Kidney
serves as a reservoir for urine
Bladder
folds in bladder wall
Rugae
normal capacity of the bladder
300-600 mL
base of the bladder
Trigone
smooth muscle fiber that allow
the bladder to expand as it fills and contract to release urine
Detrusor muscle
where vagina, urethra, rectum pass
through
Pelvic floor
expulsion of waste products from
the body through the skin, lungs, kidney, rectum
Elimination
process of emptying the urinary
bladder
Urination
special sensory nerve endings in bladder wall. Stimulated by pressure
when urine collects in the bladder
Stretch Receptors
volume of urine excreted in 24
hours
1000-2000 mL
chief solute in urine
Urea
normal volume of urine excreted per hour
30 mL
involuntary passage of urine
Enuresis
“bed wetting”. Involuntary
passage of urine during sleep
Nocturnal enuresis
it increase urine formation by
preventing the reabsorption of water and electrolytes.
Diuretics
when kidneys stop producing
urine
Renal Failure
low urine output
Oliguria
decrease client’s awareness to void
Spinal anesthetics
production of abnormally large
amounts of urine
Polyuria
absence of urine
Anuria
technique by which fluids and
molecules pass through a semi-permeable membrane based on osmosis
Renal Dialysis
client’s blood flow pass through
vascular catheters, passes by the dialysis solution in an external machine then return to
client
Hemodialysis
dialysis solution is instilled
into the abdominal cavity through a catheter, allowed to rest while the fluid and molecules exchange and then removed through the catheter
Peritoneal Dialysis:
