Filtration: Afferent blood is filtered through glomerulus and water, sugar, salts, and waste are absorbed into Bowman capsule which is continuous with the tubule.

Reabsorption: Efferent capillaries surrounding tubule reabsorb all of the sugar, most of the water and some of the salts.

Secretion: As capillaries go from arterial to venous, waste products of metabolism are secreted by the venules such as acids, drugs, and potassium from the bloodstream into the tubule.
