The excretory system primarily removes metabolic wastes such as urea, creatinine, and uric acid, which result from protein metabolism and cellular processes. It also eliminates excess salts, water, and other waste products that can accumulate in the body. These wastes are filtered from the blood by the kidneys and then excreted in urine, helping to maintain fluid and electrolyte balance.
