What are the two major functions of the urinary system?

Answer 1

Urinary system removes nitrogenous excretory product and helps to maintain internal homeostasis of the body.

Urine and nitrogenous waste (urea) are expelled from humans together.

Additionally, the renal tubules aid in the excretion of the appropriate volume of water, preserving the internal water balance.

Urine becomes acidic due to the excretion of free hydrogen ions, maintaining blood's pH of 7.4.
