FILTRATION filters by water being squeezed out of the blood in the glomerulus, from the blood by the nephrons.
FILTRATE Fluid extracted produces urine .
SELECTIVE REABSORPTION The selective uptake of solvent [water] solutes from tubule eg glucose, salt.
EXCRETION The giving off of nitrogen-containing waste products of metabolism.
RENAL ARTERY The blood vessel bringing blood to the kidney.

COLLECTING DUCT where filtrate from renal tubules is collected; the filtrate is now called urine.
RENAL PELVIS Funnel-shaped chamber that receives processed filtrate from the collecting ducts and is drained by the ureter.
excellence
CORTICAL NEPHRONS Nephrons located almost entirely in the renal cortex. These nephrons have a reduced loop of Henle.
JUXTAMEDULLARY NEPHRONS Nephrons with well-developed loops of Henle that extend deeply into the renal medulla.
