In bald eagles, the primary excretory organs are the kidneys. The kidneys play a vital role in filtering waste substances, such as urea and creatinine, from the bloodstream. These waste products are then transported to the cloaca, which is a common chamber for the digestive, urinary, and reproductive systems. From the cloaca, the waste products are eliminated from the body in the form of urine.
In addition to the kidneys, the liver also plays a significant role in the detoxification and elimination of metabolic wastes in bald eagles. The liver converts toxic substances into less harmful forms, which can then be excreted more efficiently. The liver also plays a role in producing bile, which helps in digesting fats and eliminating waste products through the feces.
