The equation that correctly describes the relationship between excretion, filtration, reabsorption, and secretion is ''excretion = filtration - reabsorption + secretion''.
Filtration is the process of removing solid particles from liquid or gaseous fluids by passing the fluid through a filter media while keeping the solid particles behind. The desired product could be either the fluid that has been cleared or the fluid that has had its solid particles removed.
The most typical illustration is brewing tea. Tea leaves and water are separated during tea preparation using a filter or sieve. The pores of the sieve will only let water through. The filtrate, in this case, water, is the liquid that has been obtained following filtration.
