Chapter 1-4 Flashcards
Primary organic component
Urea
Average daily urine output
1200ml
Primary inorganic component
Chloride
Nucleic acid breakdown in foods and cells
Uric acid
Decrease in urine output
Oliguria
Cessation of urine flow
Anuria
Increase urine output on night
Nocturia
Increase in daily urine output
Polyuria
Recommended capacity of urine
50ml
Urine specimen needed
12ml
Proper container for urine
Screw-top lid
Wide mouth
Flat bottom
Preservation that does not interfere with chemical test
Refrigeration
Preservation that prevents bacterial growth and metabolism
Boric acid
Preserves sediment in urine
Formalin
Preservative for drug analysis
Sodium flouride
For routine screening
Random specimen
For pregnancy test and orthostatic protein
First morning specimen
For quantitative chemical test
24-hour specimen
For bacterial culture
Catheterized
For routine and bacterial culture
Midstream clean catch
For bladder urine and cytology
Suprapubic aspiration
For prostatic infection
Three-glass collection
Nephron component
Juxtamedullary
Cortical nephron
Kidney’s functional unit
Nephron
Its function is to concentrate urine
Juxtamedullary
Its function is to remove waste and reabsorption
Cortical nephron
Increased specific gravity
Decrease insulin
Increase glucose
Diabetes mellitus
Decrease specific gravity
Decrease prod of ADH
Diabetes insipidus
It is produced by kidney
Urine
4 clearance test
Creatinine
Beta2-microglobulin
Cystatin C
Radioisotopes
Specific gravity of the final urine product
1.010
It measures only the number of particles in a solution
Osmolality
Two major function of tubular secretion
Eliminating waste products
Acid-base balance
Prevents excessive reabsorption of water in medulla through the ascending loop of henle
Countercurrent mechanism
Movement of molecules across a membrane as a result of electrical potential on opposite sides of the membrane
Passive transport
The substance to be reabsorbed must combine with a carrier protein which transfers the substance across the cell
Active transport
Substance/s absorbed by PCT
Glucose Amino acid Sodium Water Urea
Substance/s absorbed by DCT
Sodium
Component of juxtaglomerular apparatus
Juxtaglomerular cells
Macula densa
Maintains the glomerular blood pressure at a relatively constant rate regardless of fluctuations in blood pressure
Juxtaglomerular apparatus
