Verified step by step guidance1
Step 1: Understand the function of each body system listed in the problem. The integumentary system primarily protects the body and regulates temperature through the skin.
Step 2: Recognize that the respiratory system is mainly responsible for gas exchange, removing carbon dioxide from the blood and bringing in oxygen.
Step 3: Know that the digestive system breaks down food, absorbs nutrients, and eliminates solid waste, but it does not filter blood to form urine.
Step 4: Identify that the urinary system, also known as the excretory system, filters blood through the kidneys to remove metabolic wastes and excess substances, forming urine.
Step 5: Conclude that the urinary system is the correct answer because it is specialized in filtering blood and producing urine to remove metabolic wastes.
