Explanation:
Detailed explanation-1: -Over 70% the filtrate is reabsorbed here. In addition, many important solutes (glucose, amino acids, bicarbonate) are actively transported out of the proximal tubule such that their concentrations are normally extremely low in the remaining fluid.
Detailed explanation-2: -Thick ascending limb. The thick ascending limb of the Loop of Henle (TAL) is the predominant site of magnesium reabsorption in the kidney, reabsorbing approximately 60% of filtered magnesium 28, 31.
Detailed explanation-3: -Nearly 99 percent of the glomerular filtrate is reabsorbed by the renal tubules.
