Rids the body of wastes

• A. Excretory System
• B. Respiratory System
• C. Circulatory System
• D. Integumentary System

Answer: (A)

Removing wastes from the body is the job of the excretory system. It works mainly through the kidneys, which filter blood to form urine and carry away nitrogenous wastes like urea, plus excess water and salts, helping maintain the body's chemical balance. This system includes the kidneys, ureters, bladder, and urethra, all coordinating to keep the internal environment clean and stable. Other systems contribute to waste handling too: the respiratory system expels carbon dioxide and some water vapor; the circulatory system transports wastes to disposal sites; the skin can excrete small amounts of waste via sweat. But the excretory system is the primary mechanism for ridding the body of wastes.
