Quizplus · Accepted Answer

The filtrate that drips from the renal papillae into the calyces has undergone reabsorption and secretion processes in the nephron, leading to a higher concentration of waste products such as urea. It may also have lost up to 99% of its original volume due to water reabsorption. This final product is called urine. Therefore, option D is the most accurate answer.
