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.
The kidney also plays a major role in regulating levels of various minerals such as calcium, sodium, and potassium in the blood. 1  As the first step in filtration, blood is delivered into the glomeruli by microscopic leaky blood vessels called capillaries. 2  The tubules are the next step in the filtration process.
