Verified step by step guidance

Step 1: Begin by understanding the concept of metabolic waste. Metabolic waste refers to substances produced during metabolic processes in the body, such as urea, carbon dioxide, and excess salts, which need to be eliminated to maintain homeostasis.

Step 2: Review the primary functions of each body system listed in the problem. For example: The digestive system breaks down food and absorbs nutrients, the endocrine system regulates hormones, the respiratory system facilitates gas exchange, and the urinary system filters blood and removes waste products like urea and excess water.

Step 3: Focus on the urinary system. The urinary system includes the kidneys, ureters, bladder, and urethra. Its primary role is to filter blood, remove nitrogenous waste (like urea), and regulate water and electrolyte balance.

Step 4: Compare the urinary system's function to the other systems listed. While the respiratory system eliminates carbon dioxide and the digestive system removes solid waste, the urinary system is specifically responsible for eliminating liquid metabolic waste, such as urea and creatinine.

Step 5: Conclude that the urinary system is the correct answer because it is primarily responsible for eliminating metabolic waste products from the body, ensuring proper filtration and excretion.
