The urinary system

The urinary system is a group of organs responsible for the elimination of bodily waste among other important functions. Below is a brief introduction to the system, and its main components.


The urinary system in brief

The main purpose of the urinary system, also known as the urinary tract, is to eliminate waste from the body through the excretion of urine. The system also handles other important functions such as the regulation of blood pressure and volume, controlling of electrolyte and metabolite levels and regulation of blood acidity. If you experience problems passing urine or symptoms of urinary tract obstructions, you should always consult your doctor for a medical examination.
