Urine
Bowman’s Capsule: The portion of the nephron that receives the glomerular filtrate.
Cortex: The outer layer or portion of an organ.
Distal Convoluted Tubule: The portion of a renal tubule that empties into the collecting tubule.
Diuresis: Output of an abnormally large urine volume.
Glomerular Filtrate: The fluid that passes from the blood into the nephron and from which urine is formed.
Glomerulus (pl. glomeruli): A small bundle of capillaries that is the filtering portion of the nephron.
Loop of Henle: The U-shaped portion of the renal tubule between its proximal and distal portions.
Medulla: The inner or central portion of an organ.
Nephron: The structural and functional unit of the kidney.
Proximal Convoluted Tubule: The portion of a renal tubule that collects the filtrate from Bowman’s capsule.
Pyelitis: Inflammation of the renal pelvis.
Pyelonephritis: Inflammation of the kidney and renal pelvis.
Renal Pelvis: The cavity in the kidney that receives urine from the renal tubules and the site where the ureter enters the kidney.
Renal Threshold: The blood concentration above which a substance not normally excreted by the kidneys appears in urine.
Tubular Necrosis: Death of the tissue comprising the renal tubules.
Anuria: Complete failure of kidney function and suppression of urine production; absence of urine production.
Clean-Catch Urine: A midstream urine sample collected after the urethral opening and surrounding tissues have been cleansed.
Midstream Urine: A urine sample collected in the middle of voiding.
Nocturia: Excessive urination at night.
Oliguria: Decreased production of urine
