Kidney

Paired organ important in homeostasis.

Function may be measured by creatinine clearance which may also be estimated.

The kidneys have significant biological reserve. By the time the serum creatinine rises - usually the first sign of renal impairment, the kidneys have lost a high proportion (e.g. 75-90%) of their physiological function.

Apart from blood, the kidney was the first organ successfully transplanted, in 1954.
