Which organs are responsible for eliminating water and waste products from the body?

1. Liver

2. Heart

3. Kidneys

4. Pancreas

The correct answer is: Kidneys

The kidneys play a crucial role in the body's waste elimination and fluid regulation processes. They serve as the primary organs responsible for filtering blood, removing excess water, electrolytes, and metabolic waste products. This process occurs through the formation of urine, which collects in the bladder before being excreted from the body. The kidneys maintain homeostasis by regulating the body’s water balance, electrolyte levels, and the elimination of urea and creatinine, both of which are metabolic byproducts. The liver processes nutrients and detoxifies substances, but its primary function is not to eliminate water and waste products directly. The heart is responsible for pumping blood but does not participate in the elimination of waste. The pancreas mainly aids in digestion and regulates blood sugar levels, but it is not involved in directly filtering waste from the bloodstream. The unique and essential function of the kidneys makes them the correct answer in this context.
