The kidney is an organ that collects wastes and excess water from the blood and sends them to the bladder where they are stored before being removed from the body. which two systems work together to perform this function?

Urinary system and  Circulatory system

Explanation:

Blood flows to the kidney through the renal artery until the blood reaches the glomerulus, an area of the nephron where the blood is filtered and where the waste to be expelled and the substances that are still useful for the body are separated. Once the urine is filtered, there are substances that go back to the blood because they are still very useful to the body. From the kidney, urine passes to the renal pelvis, and then to the ureter, a very long tube that connects the kidney to the bladder Subsequently, the bladder stores the urine to be eliminated by another final section tube, called the urethra
