_____________________________________________________

Final answer:

The urinary system helps to maintain the balance of water and electrolytes in the body, aiding in the body's homeostasis. This is achieved through the filtration of the blood by the kidneys, expelling excess substances and waste products.

Explanation:

The urinary system plays an integral role in our body's homeostasis by maintaining the balance of water and electrolytes (Option B). This is accomplished by filtration of the blood in the kidneys, which remove waste products and excess substances, including water and electrolytes. For instance, if our body has a high level of sodium, the kidneys filter out the excess and excrete it into the urine. Similarly, if there is too much water, it will also be excreted. This delicate balance ensures our cells can function properly in the correct environment.
