Presentation transcript:

Urine Volume Regulation

Volume Regulation 1. Antidiuretic hormone (ADH) – IF blood volume LOW – Pituitary releases ADH

Volume Regulation - ADH causes Water reabsorption DCT and Collecting tubules

Volume Regulation 2. Aldosterone – IF blood volume LOW – Adrenal cortex releases Aldosterone

Volume Regulation - Aldosterone causes absorption of Sodium DCT and Collecting tubules Results in Water absorption from Collecting tubules

Volume Regulation 3. Amount of solutes in Renal tubule – The more solutes in urine, the more Water in urine

Renal Disease

1. Renal Obstruction o Urine “backup” causing inflammation of the Pelvis and Calyces

Renal Obstruction o Renal Calculi (kidney stones) -Mineral crystallization -Most common - Calcium

Renal Obstruction o May obstruct the ureter oTreatment -Pass it -Break it - Lithotripsy -Surgery

2. Proteinuria oProteins in the urine oDamaged Bowman’s capsule

3. Glycosuria oGlucose in the urine oExcess cannot be reabsorbed

4. Hematuria oBlood in the urine oIndicator of kidney disease

5. Ketonuria oKetones in the urine oIndicates diabetes or starvation (fat metabolism)

6. Casts oMolds of cells formed in renal tubules oIndicator of nephron disease

RBC Cast

WBC Cast
