Nephrons. Blood is filtered in the nephrons, and the majority of the filtered material returns to the blood. It removes nitrogenous waste, and balances mineral ions and water levels in the blood.; Each nephron is about 3cm long, and there are 1.5 million per kidney. This provides the body with several kilometres for reabsorption of water, glucose, salts etc.
