The excretory system is responsible for removing waste products and maintaining the body's internal environment. It includes organs such as the kidneys, liver, lungs, and skin. The kidneys play a crucial role by filtering blood to remove waste products like urea, as well as excess salts and water, forming urine. The liver helps detoxify harmful substances, while the lungs expel carbon dioxide. The skin eliminates waste through sweat. This system is essential for regulating the body's chemical balance, preventing the buildup of toxins, and ensuring proper hydration and electrolyte levels.
