Which body system rids the body of waste and filters the blood?

• A. Digestive
• B. Circulatory
• C. Respiratory
• D. Urinary

Answer: (D)

The urinary system cleans the blood and removes waste from the body. The kidneys filter wastes and excess substances from the bloodstream, producing urine. This process helps regulate fluid balance, electrolyte levels, and the body's acid-base balance. Urine is then stored in the bladder and eliminated through the urethra. Other systems have different primary roles: the digestive system handles breaking down food and eliminating solid waste; the circulatory system transports blood, nutrients, and waste throughout the body; the respiratory system exchanges gases like oxygen and carbon dioxide. While they play roles in waste processing, the urinary system is the main one that filters the blood and rids the body of liquid waste.
