In which of the following the major portion of glomerular filtrate is absorbed? (LQ)



A Collecting duct

B Distal convoluted tubule

C Loop of Henle

D Proximal segment by active reabsorption of Na+

Ans. D Proximal segment by active reabsorption of Na+
  1. Many substances are actively transported out of the fluid in the proximal tubule, but fluid obtained by micropuncture remains essentially isosmotic to the end of the proximal tubule.
  2. Therefore in the proximal tubule, water moves passively out of the tubule along the osmotic gradients setup by the active transport of solute and isotonicity untamed 60— 70% of the filtered solute and 60— 70% of the filtered water have been removed by the time the filtrate reaches the end of the proximal tubule.
