NEPHRONS - The Kidneys' Filtration Units. Nephrons are microscopic tube-like structures in the kidneys that filter the blood and cause wastes to be removed. They are the most basic structures of the kidney's anatomy, and are an integral part of the urinary system. Each kidney contains over one million of them.
  Within the nephron (the functional unit of the kidneys), filtration occurs in the glomerolus. The filtered fluid is called filtrate. Reabsorption of filtrate occurs in a â¦ few places within the nephron, however, the majority of reabsorption takes place in the proximal convoluted tube.
