Why is a kidney important to a salmon?

Answer 1

The kidney is crucial to a salmon because it plays a vital role in osmoregulation, helping the fish maintain the balance of salts and water in its body, especially as it migrates between freshwater and saltwater environments. Additionally, the kidney aids in excreting waste products and regulating blood pressure. By efficiently managing these processes, the kidney supports the salmon's overall health and adaptability in various aquatic habitats.
