CONT

À côté de [la] réabsorption tubulaire, il existe une sécrétion tubulaire qui permet le passage de molécules du sang des capillaires péri-tubulaires vers le filtrat à travers la cellule du tubule. Elle permet d'éliminer dans l'urine des substances indésirables ou en excès qui ont été insuffisamment filtrées au niveau du glomérule. [...] Ce mécanisme de sécrétion tubulaire est important pour la régulation de l'homéostasie des protons et du potassium.
