Question

Quizplus · Accepted Answer

The proximal tubule of the kidney nephron absorbs sodium in order to regulate the body's salt and water balance. Triglyceride is a type of lipid and is not a solute that would be absorbed in the proximal tubule. Carbon dioxide is eliminated through the respiratory system and is not filtered by the kidney. Urea is a waste product of protein metabolism and is also excreted by the kidney rather than absorbed.
