Why does the body use other body parts to eliminate its own wastes?

The body uses various organs and systems to eliminate waste to maintain homeostasis and overall health. Different waste products require specific elimination methods; for instance, the kidneys filter blood to remove toxins and excess fluids, while the liver processes and detoxifies substances. Additionally, the respiratory system expels carbon dioxide, and the skin eliminates waste through sweating. This multi-organ approach ensures efficient removal of harmful substances and balances bodily functions.
