What organ functions to filter blood and produce urine?

The kidneys are the organs responsible for filtering blood and producing urine. They play a crucial role in the urinary system by removing waste products and excess substances from the bloodstream. This filtration process is essential for maintaining fluid balance, electrolyte levels, and blood pressure in the body. The kidneys also help regulate various metabolic functions and produce hormones that are important for red blood cell production and bone health.

While the liver is involved in filtering toxins from the blood, its primary function is more related to metabolism and detoxification rather than urine production. The heart is responsible for pumping blood throughout the body, and the lungs are involved in gas exchange, specifically oxygen intake and carbon dioxide removal. Therefore, the kidneys stand out as the dedicated organs for filtration and urine generation.
