Proper functioning of body cells and processes requires solute concentrations to be maintained within a narrow range.Which of the following solutes would be absorbed by the proximal tubule of the kidney nephron?

Question

Quizplus · Accepted Answer

The proximal tubule of the kidney nephron absorbs sodium, which is essential for maintaining proper solute concentrations in the body. Triglycerides are a type of fat and are not absorbed by the proximal tubule. Urea is a waste product that is mainly excreted by the kidney, but it is primarily reabsorbed in the loop of Henle, not the proximal tubule. Carbon dioxide is a gas that is not absorbed by the proximal tubule or any other part of the nephron.
