Answer» B. Filtration Explanation: The NEPHRONS work through a two-step process: the glomerulus filters your blood, and the tubule returns NEEDED substances to your blood and removes WASTES. Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes. |
