Verified step by step guidance

Step 1: Understand the function of each organ listed in the problem. The heart pumps blood throughout the body, the lungs are responsible for gas exchange (oxygen and carbon dioxide), the liver processes and detoxifies substances, and the kidneys filter blood to remove waste and regulate fluid balance.

Step 2: Focus on the organ responsible for detoxification. The liver plays a central role in breaking down toxins, metabolizing drugs, and producing bile to aid in digestion.

Step 3: Learn about the liver's detoxification process. It uses enzymes to convert harmful substances into less toxic forms, which are then excreted through urine or bile.

Step 4: Compare the liver's detoxification role to the functions of the other organs listed. While the kidneys filter waste and the lungs remove carbon dioxide, neither is primarily responsible for breaking down toxins like the liver.

Step 5: Conclude that the liver is the correct answer based on its unique role in detoxification and metabolism, as supported by its physiological functions.
