Which body system helps rid the body of wastes, toxins, and excess water or nutrients, with major organs including kidneys, ureters, bladder, urethra, skin, and lungs?

• A. Digestive system
• B. Excretory system
• C. Respiratory system
• D. Immune system

Answer: (B)

This question tests understanding of which body system is responsible for removing wastes and regulating fluid balance. The excretory system handles exactly that, using organs like the kidneys, ureters, bladder, and urethra to filter blood, form and transport urine, store it, and excrete it. It also involves the skin, which releases water and salts through sweat, and the lungs, which expel carbon dioxide and water vapor. While other systems touch on waste in different ways—digestion eliminates solid waste from food, and respiration handles gas exchange—the combined functions of these organs fit the excretory system, making it the correct choice.
