How does the urinary system help maintain homeostasis?
Answer (1)
The urinary system plays a major role in maintaining homeostasis—the stable internal environment of the body—by regulating:Fluid and electrolyte balanceWaste removalBlood pressurepH levelsMain organs involved:Kidneys – Filter the blood, remove waste products like urea, uric acid, and creatinine. They also regulate water levels and produce urine.Ureters – Transport urine from kidneys to bladder.Bladder – Stores urine until it’s excreted.Urethra – Pathway for urine to exit the body.The kidneys also regulate:Electrolytes (like sodium, potassium, and calcium)Acid-base balance by excreting hydrogen ions or bicarbonateBlood pressure via the renin-angiotensin systemRed blood cell production through erythropoietin hormoneWithout the urinary system, toxic wastes would accumulate, leading to serious illness. Disorders like kidney failure require dialysis or transplant to restore these vital homeostatic functions.
