What is the function of the urinary system?
Maintain equilibrium by excretion of urine
Detoxify blood
Regulate blood pressure
Balance pH, minerals, iron, and salt
How does urine develop?
Blood enters the KD via renal artery and branches into the interlobar arteries
They turn into afferent arterioles which carry blood into the glomerulus of the nephron
The glomerulus filters blood
Waste is excreted in urine
Useful substances are reabsorbed
What is the nephron and what does it consist of?
The functional unit of the kindey
Renal corspuscle
proximal and distal convulted tubule
Henle's loop
collecting tubule
Adult Kidney
Distended Urinary Bladder Wall
Female Urethra
Male Urethra
9-12 X 4-6 X 2.5-4
28-34cm (l) 6mm (w)
4cm length
20cm length
Normal BUN level and what it represents
26mg/dl (normal renal function)
Normal Creatinine level and what it represents
1.1mg/dl (normal renal function)
Elevation of BUN and Cr could mean:
Renal disease
Hormones that affect the kidney
Aldosterone-increases salt and water reabsorbtion
Renin-maintains BP
ADH-increases water reabsorption
Filtration takes place in the:
Renal cortex
Reabsorbtion takes place in the:
Function of the medullary pyramids
To convey urine to the calyces
How urine is transported to the renal sinus
Minor calyces convey urine to the major calyces
They then dump urine into the renal sinus
How much blood does the KD filter?
1200ml blood/minute
How much urine does the KD produce and what is it made up of?
150ml urine/day
95% water
5% nitrogenous waste and inorganic salts
What is in nitrogenous waste?
Byproducts of metabolism
Which two lab tests measure nitrogenous waste?
BUN and Cr
(measure the bodys ability to get rid of waste)
What does the specific gravity test do?
Assesses the ability to concentrate urine-it shows how much dissolved material is present in the KD
High=more dissolved solutes in urine
Specific Gravity
RBC in urine
WBC in urine
renal trauma, calculi, infarction
renal infection
glomerulonephritis, nephrotic syndrome, renal vein thrombosis
Renal failure, obstructive uropathy, dehydration, hemorrhage
Renal failure
Renal disease
6 protective mechanisms
Decrease renal capillary bed resistance
Move blood outer to inner cortex
Makes erythropoitin
Makes renin
Secretes aldostereone
What are the ureters?
Tubes that carry urine from each kidney to the bladder (a temp. storage for the urine until it is excreted through the urethra)
What is the true capsule?
A protective covering that surrounds the renal cortex
surgical diseases of the urinary system
Medical diseases of the KD
Diagnostic interpretation
