H+ and HCO3-. 1  The secretion of H+ in this section of the nephron is mainly a result of the Na+/H+ antiporter in the apical membrane using secondary active transport. 2  HCO3- is reabsorbed here in a different way to other substances. 3  Link to Article.
These substances are water, glucose, amino acids, vitamins, bicarbonate ions, and the chloride salts of calcium, magnesium, sodium and potassium. Reabsorption starts in the proximal tubules and continues through the Henle's loop, to the distal tubule and then to the collecting tubules.bout 99% of the initial filtrate from the glomerulus is reabsorbed by the nephron and returned to the blood in the peritubular capillaries. o The number of nephrons does not increase after birth. Growth of the kidney is due to the enlargement of existing nephrons not due to an increase in their number.
