Vedclass · Answer

(D) The correct answer is $D$. Approximately $65\%$ of the glomerular filtrate is normally reabsorbed in the proximal convoluted tubule $(PCT)$ before reaching the loop of Henle. The $PCT$ is responsible for the reabsorption of essential nutrients such as glucose,amino acids,vitamins,hormones,$Na^+$,$K^+$,$Cl^-$,phosphates,bicarbonates,water,and urea. If the $PCT$ is removed,the reabsorption of these solutes and water is significantly impaired. Consequently,a larger volume of fluid reaches the distal parts of the nephron,but because the primary reabsorptive site for water and solutes is absent,the final urine produced will be more concentrated due to the inability to regulate the osmotic balance effectively.

Removal of the proximal convoluted tubule from the nephron will result in:
