The kidneys are the organs responsible for filtering waste from the blood of vertebrates. Amphibians have just one kidney, but all other vertebrates have paired kidneys, and the structure of these organs in all vertebrates is generally the same.
In humans, blood enters the kidneys through the renal artery and is filtered through millions of nephrons. The nephrons work to remove waste and water from the blood, and the filtered blood is returned to the body through the renal vein. Any waste and water removed from the blood passes out of the kidney through the ureters and into the bladder.
Kidneys are a vital part of maintaining homeostasis in vertebrates as they work to remove excess mineral content and potentially harmful substances from the blood.
