Identify the main function described in the problem: filtering the blood and eliminating metabolic waste.
Consider the primary functions of each body system listed: Endocrine, Urinary, Respiratory, and Digestive.
Recall that the Endocrine System is primarily responsible for hormone production and regulation, not waste elimination.
