URINARY SYSTEM MULTI PAL CHOICE QUESTIONS 

The Urinary System is a group of organs, also known as the renal system or urinary tract, excretory system consists of the two kidneys, two ureters, bladder, and the urethra. The purpose of the urinary system is produces, stores and eliminates urine & waste product (ex- ammonia, urea, uric acid, creatinine & bilirubin) from the body, urinary system also work as regulation of blood plasma electrolyte and blood osmolarity, blood pH, blood volume and BP. Production of hormones also a major function of renal system.
