Question

Quizplus · Accepted Answer

The movement of solutes from the blood in capillaries into adjacent tubules describes the process of secretion, where substances are selectively transported from the peritubular capillaries into the renal tubules. Filtration is the process where blood pressure forces water and small solutes across the filtration membrane, while reabsorption occurs when useful substances are transported from renal tubules back into the blood. Elimination and excretion refer to the final removal of waste products from the body through urine.
