Which organ is primarily responsible for filtering toxins and waste from the body?

• A. Heart
• B. Liver
• C. Kidneys
• D. Lungs

Answer: (C)

The kidneys are primarily responsible for filtering toxins and waste from the body. They play a crucial role in maintaining homeostasis by regulating the composition of blood, removing waste products, and balancing electrolytes and fluids. The kidneys filter out waste materials, including urea and creatinine, which are byproducts of protein metabolism, as well as excess salts and water, excreting them in the form of urine. In addition to waste elimination, the kidneys also help regulate blood pressure and produce hormones that are vital for red blood cell production and calcium metabolism. This multifaceted function establishes the kidneys as essential organs for detoxification and waste management in the body. While the liver indeed has a significant role in processing chemicals and metabolizing drugs, its function is more about transforming toxins into less harmful substances rather than directly filtering them out of the bloodstream like the kidneys do. The heart and lungs, while vital to circulation and respiration, respectively, do not primarily function in toxin removal or filtration in the same direct manner as the kidneys.
