Question

Quizplus · Accepted Answer

Hydrogen ions are actively secreted into the filtrate by both the proximal and distal convoluted tubules in order to maintain acid-base balance in the body. The collecting duct and Bowman's capsule do not participate in this process, and while the loop of Henle does play a role in ion regulation, it primarily functions in reabsorption rather than secretion of ions.
