Verified step by step guidance

1. Begin by identifying the primary functions of each organ listed in the problem.
2. Understand that the kidney is responsible for filtering blood to remove waste products and excess substances, forming urine.
3. Recognize that the lungs are involved in gas exchange, primarily oxygen and carbon dioxide, between the air and the bloodstream.
4. Note that the heart's main function is to pump blood throughout the body, not to produce insulin. Insulin is produced by the pancreas.
5. Acknowledge that the liver plays a key role in detoxifying blood, metabolizing drugs, and processing nutrients.
