The organ in the excretory system that filters blood is the kidney.
The organ in the excretory system that filters blood is the kidney. To arrive at this answer, we can eliminate the other options.
The ureter is a tube that carries urine from the kidneys to the bladder - it does not filter blood.
The bladder is a storage organ for urine - it does not directly filter blood.
The urethra is the tube through which urine is expelled from the body - it does not filter blood.
Therefore, the correct answer is the kidney, as it is responsible for filtering waste substances from the blood and producing urine.
