Filtration is the stage of urine production that involves the removal of substances from the bloodstream. This occurs in the glomerulus of the kidney, where blood is filtered and small molecules, such as electrolytes, water, and waste products, are passed into the nephron to continue through the process of urine formation. Reabsorption involves returning substances that were filtered back into the bloodstream. Secretion is the stage where additional substances are added to the filtrate. Excretion is the final stage where urine is eliminated from the body.
