WebTubular secretion can be either active or passive or co-transport. Substances mainly secreted into renal tubule are; H+, K+, NH3, urea, Creatinine, histamine and drugs like penicillin. The kidney's ability to perform many of its functions depends on the three fundamental functions of filtration, reabsorption, and secretion, whose sum is called renal clearance or renal excretion.
