nephron
nephron The excretory unit of the vertebrate
kidney (see illustration). Many constituents of the blood are filtered from the glomerulus into the
Bowman's capsule at one end of the nephron. The
glomerular filtrate passes along the length of the nephron and some of its water, plus some salts, glucose, and amino acids, are reabsorbed into the surrounding blood capillaries (see
proximal convoluted tubule;
loop of Henle;
distal convoluted tubule). More water is reabsorbed in the
collecting duct, and the resulting concentrated solution of nitrogen-containing waste matter (
urea in most mammals) plus inorganic salts drains from the collecting ducts of the nephrons and is discharged as urine into the ureter.
