Question: what molecules are reabsorbed in each tubular element of the nephron?
Answer: Potassium ion, sodium chloride, calcium ion, amino acids, glucose, bicarbonate ion and water are reabsorbed back into the blood stream. Any filtered amino acids and glucose are also reabsorbed back into the blood stream. Hydrogen ions, uric acid and drugs are secreted from the blood into the proximal convoluted tubule.
