Each kidney contains millions of nephrons working in parallel. The nephron is the functional unit of the kidney, consisting of tiny capillaries that convert blood into urine. Chronic kidney disease can permanently destroy up to 50% of nephrons, dramatically reducing the kidney's ability to clear waste. Because the nephron is entirely vascular, the kidney is especially vulnerable to glucose-driven capillary damage.
