Nephrons are the filtering structures of the kidneys. The
kidneys contain millions and millions of these tiny filtering structures that
are responsible for cleaning the blood. Nephrons are responsible for removing
excess water, wastes, and other substances in the blood that are not needed by
the body. They also return necessary substances (e.g. sodium, potassium,
phosphorus) whenever the body runs low in supply.
If these nephrons are damaged, blood will not be properly
filtered. As a result, the kidney will have different diseases and this might
lead to kidney and multiple organ failure.
