Quizplus · Accepted Answer

The process of filtration in the glomerulus is mainly driven by arterial blood pressure. Blood pressure forces fluid and small molecules out of the capillaries and into the glomerulus. This process is regulated by the size and charge of the molecules passing through the membrane. Active transport occurs mainly in the tubules, where substances are selectively reabsorbed. Venous blood pressure and osmotic pressure play a minor role in filtration. Secretion is also a process that occurs mainly in the tubules, where substances are actively secreted into the tubular fluid.
