Verified step by step guidance

Step 1: Begin by identifying the primary function of urinary elimination, which involves the removal of waste products and excess substances from the blood and the regulation of fluid and electrolyte balance in the body.

Step 2: Understand that the organ system responsible for urinary elimination is the urinary system, which includes the kidneys, ureters, bladder, and urethra. These organs work together to filter blood, produce urine, and excrete it from the body.

Step 3: Compare the functions of the other organ systems listed in the problem: the digestive system (responsible for nutrient absorption and waste elimination via feces), the endocrine system (responsible for hormone production and regulation), and the respiratory system (responsible for gas exchange and removal of carbon dioxide). None of these systems are primarily responsible for urinary elimination.

Step 4: Recognize that the urinary system is specifically designed for the excretion of liquid waste (urine) and plays a critical role in maintaining homeostasis by regulating blood pressure, electrolyte levels, and pH balance.

Step 5: Conclude that the correct answer is the urinary system, as it is the organ system primarily responsible for urinary elimination in the human body.
