• A. Nephrons actively transport uric acid and other nitrogenous waste products into the proximal and distal convoluted tubules, from where it is collected to form urine
• B. The blood is filtered to retain cells and large plasma , proteins within the blood, the remaining filtrate passes through the proximal and distal convoluted tubules, where needed substances are reabsorbed by active transport
• C. Nephrons filter out the nitrogenous waste which is passed through the proximal and distal convoluted tubules and collected by the collecting duct as urine
• D. Nephrons convert nitrogenous waste to uric acid and pass it out as urine
