Reabsorption

Water and many solutes (e.g., Na+, Cl−, HCO3−, glucose, amino acids, urea, Ca2+, Mg2+, phosphate, lactate & citrate) are reabsorbed from the glomerular filtrate into the peritubular capillary blood.

Secretion

A few substances (e.g., organic acids,

organic bases, K+) are secreted from peritubular capillary blood into tubular fluid for excreting substances in the urine.
