ADH and factors affecting urine composition
What is ADH?
ADH - Anti Diuretic Hormone
Produced in the hypothalamus
Released by the pituitary gland
Excess of water in body
Detected by the receptors in the hypothalamus
Pituitary gland secretes less/no ADH
Large volumes of dilute urine produced
Water concentration in blood returns to normal
Components present in urine
RBCs (Greater than 5 counts per HPF)
WBCs (Greater than 5 counts of HPF)
HPF = High power field, LPF = low power fields
Kidney Stone Indicators
Crystaline Crystal
Bilirubin Crystal
Calcium Carbonate
Cholestrol Crystals
UTI Indicators
Bacteria (Cocci)
Bacteria (Rods)
WBCs
Nitrites
Greater than 5 count per HPF indicates injury in kidney
Factors affecting urine output
More Water intake
Dilutes the blood
Lessens production of ADH
Large volumes of dilute urine is produced
Along with water, many ions are getting taken out so makes body weak
Less water intake
Small volume of concentrated urine is produced
Concentrated blood
More production of ADH
Dehydration, can cause kidney stones due to deposits
Temperature or sweating
High temperatures cause us to sweat to cool down
water in the body decreases
Diuretics
A type of medication/beverage that causes kidney nephron to be less permeable to water
resulting urine is dilute
Ex: coffee, alcohol, etc
Insufficient water in blood
Detected by receptors in hypothalamus
Pituitary gland secretes more ADH
Less volume of concentrated urine
Water concentration returns back to normal
More water reabsorbed
