The story of the word

Each human kidney holds around a million of these, so the organ is really a bundle of filters working in parallel, and the name treats one of them as a kidney in miniature. English kept both the Greek and the Latin word for the organ, which is why the specialist is a nephrologist while the artery is renal and the gland on top is adrenal. Greek νεφρός also gave the surgical vocabulary its nephrectomy and nephritis.
