The urinary system is primarily responsible for the elimination of metabolic waste products from the body. It consists of the kidneys, ureters, bladder, and urethra, working together to filter blood, remove waste products, and regulate water and electrolyte balance. The kidneys play a crucial role in this process by filtering out toxins and waste products, such as urea and creatinine, from the bloodstream and excreting them as urine.

The other body systems mentioned do not have the primary function of waste elimination. The endocrine system is involved in hormone production and regulation, impacting various bodily functions but not specifically focused on waste removal. The female and male reproductive systems are geared towards reproduction and sexual health, rather than the elimination of metabolic waste. Therefore, the urinary system is the correct choice for the elimination of metabolic waste products.
