The organ in the excretory system that filters blood is the kidney.

The organ in the excretory system that filters blood is the kidney. The kidneys are two bean-shaped organs located in the upper abdomen, one on each side of the spine. They play a crucial role in maintaining the body's homeostasis by filtering waste products and excess water from the blood, thus forming urine. The kidneys ensure that the body maintains a proper balance of electrolytes, water, and acid levels by filtering and excreting waste products, such as urea, creatinine, and excess minerals like sodium and potassium, from the bloodstream. They also help regulate blood pressure and produce hormones that stimulate red blood cell production.
