"Some of the materials that exit the blood can be returned to the blood."

Explanation: Blood plasma is filtered into the nephron (glomerular filtrate), then useful substances (eg, glucose, most water, ions, amino acids) are reabsorbed back into the peritubular capillaries while wastes remain or are secreted into the tubule and excreted as urine.
