Secretion is the process in urinary system that leads to the elimination of excessive substances like sodium and potassium in the urine.
Secretion is the process of transfer of waste substances from the blood capillaries into the renal tubule. The waste substances can be ions like sodium, potassium, or hydrogen. The segment of the renal tubule that performs secretion is the proximal convoluted tubule.
Urinary system is also called the excretion system where all the waste ions, minerals and water is transferred out from the body in the form of urine. Kidneys are the key organs of the urinary system. They filter out the impurities from the blood and excrete it out through the urethra by a process called micturition.
