25.Maintenance of body potassium levels is primarily by tubular A. Absorption in PCT B. Secretion in DCT C. Absorption in DCT D. Secretion in PCT
Option B The distal convolutes tubule(DCT) is a portion of the kidney between the loop of Henle and the collecting tubule. selective secretion of hydrogen and potassium ions and NH3 to maintain the pH and sodium-potassium balance in the blood. Hence Maintenance of body potassium levels is primarily by tubular secretion in DCT.
