Verified step by step guidance

Step 1: Begin by identifying the primary function described in the question: filtering the blood and eliminating liquid metabolic waste. This is a key physiological process related to maintaining homeostasis in the body.

Step 2: Recall the role of the urinary system, which includes organs such as the kidneys, ureters, bladder, and urethra. The kidneys filter the blood to remove waste products like urea, excess salts, and water, forming urine.

Step 3: Compare the urinary system's function to the other systems listed: the endocrine system regulates hormones, the digestive system processes food and absorbs nutrients, and the respiratory system facilitates gas exchange (oxygen and carbon dioxide). None of these systems are primarily responsible for filtering blood and eliminating liquid waste.

Step 4: Understand that the urinary system is specifically designed for excretion of liquid metabolic waste, making it the correct answer based on the function described.

Step 5: Conclude that the urinary system is the body system responsible for filtering the blood and eliminating liquid metabolic waste, as its primary function aligns with the description provided in the question.
