Tubular Secretion Certain molecules (e.g., H + and penicillin) are actively secreted from the peritubular capillary network into the convoluted tubules. Glomerular Filtration Water, salts, nutrient molecules, and waste molecules move from the glomerulus to the inside of the glomerular capsule. These small molecules are called the glomerular filtrate.
