What organ is responsible for filtering blood and producing urine?

The kidney is the organ responsible for filtering blood and producing urine. It plays a crucial role in the body's waste management and regulation of fluid and electrolyte balance. The kidneys filter out toxins, excess substances, and metabolic waste from the bloodstream, which they then convert into urine. This urine is subsequently transported to the bladder for temporary storage before being excreted from the body.

In addition to waste removal, the kidneys also perform important functions such as regulating blood pressure, maintaining acid-base homeostasis, and producing hormones like erythropoietin, which stimulates red blood cell production. This vital organ ensures that harmful substances are efficiently eliminated while preserving necessary components in the bloodstream, making it essential for overall health and bodily function.
