What is the primary function of the urinary system?

The primary function of the urinary system is to remove wastes from the body. This system is responsible for filtering the blood, eliminating waste products and excess substances, and maintaining the body's fluid and electrolyte balance. The kidneys play a key role in this process by filtering out toxins and waste materials, which are then excreted as urine through the ureters to the bladder and ultimately out of the body.

This function is crucial for maintaining homeostasis, which includes regulating the volume and composition of body fluids. When the urinary system is functioning properly, it ensures that harmful substances are efficiently removed, thereby helping to prevent potential health issues related to waste accumulation and hormonal imbalances.
