Excuse my ignorance, but I've always been taught that the function of the
kidneys was to filter the blood and remove impurities, poisons, toxins, and
other un-needed things to maintain proper electrolyte balance in the blood.
How could it possibly help the body to ingest these substances and send them
through the digestive system????

still looking for spring, too, but from the other perspective (did we miss it??)
