Question

Quizplus · Accepted Answer

The primary function of the distal convoluted tubule is secretion, specifically the secretion of hydrogen ions and potassium ions. It also plays a role in the regulation of calcium and sodium ions. Reabsorption mainly occurs in the proximal convoluted tubule and filtration occurs in the glomerulus. Increased retention of sodium ions is not a function of the distal convoluted tubule, but rather the collecting duct.
