is a process whose selectivity depends on the state of the pedicels of the visceral layer of Bowman's capsule

is increased when the sodium load on the macula densa is high (tubulo-glomerular feedback )

is the asymptotic value for renal clearance for any substance at very high concentrations

is a process strongly influenced by blood pressure

is a selective process by which unneeded and toxic substances are eliminated

is a process whose magnitude depends on the state of the pedicels of the podocytes

changes more than reabsorption in response to changes in blood pressure (pressure induced natriuresis)

is an unspecific process that involves all sufficiently small molecules

is a process of passive diffusion

is reduced by aldosterone

is the most important process in the elimination of lipophilic substances
