Detailed explanation-1: -The proximal convoluted tubule reabsorbs ions, water, and nutrients from the filtrate into the interstitial fluid, and actively transports toxins and drugs from the interstitial fluid into the filtrate.
Detailed explanation-2: -The proximal tubules reabsorb about 65% of water, sodium, potassium and chloride, 100% of glucose, 100% amino acids, and 85-90% of bicarbonate.
Detailed explanation-3: -Reabsorption Moves Nutrients and Water Back into the Bloodstream. The glomerulus filters water and small solutes out of the bloodstream. The resulting filtrate contains waste, but also other substances the body needs: essential ions, glucose, amino acids, and smaller proteins.
Detailed explanation-4: -Almost all glucose is reabsorbed in the proximal convoluted tubule (PCT) part of a nephron (structural and functional unit of a kidney).
