Vedclass · Answer

(C) The Distal Convoluted Tubule $(DCT)$ plays a crucial role in the regulation of blood composition. It performs conditional reabsorption of $Na^+$ and water,and is responsible for the selective secretion of hydrogen ions $(H^+)$,ammonia $(NH_3)$,and potassium ions $(K^+)$ into the filtrate. By regulating the secretion of $H^+$ and the reabsorption of $HCO_3^-$,the $DCT$ maintains the $pH$ of the blood. Additionally,the regulation of $Na^+$ and $K^+$ levels ensures the electrolyte balance of the blood. Therefore,both $pH$ and $Na-K$ balance are maintained by the $DCT$.

The main function of the $DCT$ of the nephron is to maintain the:
