Urine formation in the kidney involves three distinct processes: filtration, reabsorption, and secretion. Filtration occurs as blood is filtered through the glomerulus in the nephron, and water and small solutes are pushed through into the Bowman's capsule. Reabsorption occurs as water, ions and nutrients are reabsorbed from the filtrate back into the bloodstream in the proximal and distal convoluted tubules. Secretion occurs as additional wastes, such as excess ions and toxins, are actively transported from the blood into the filtrate in the renal tubules before the final urine is excreted from the body.
