Human feces is not an example of excretory waste. Why is this?

Human feces is not considered excretory waste because it is a byproduct of the digestive system, rather than the excretory system. Excretory waste refers to the waste products that are eliminated by the kidneys, such as urine, which contain metabolic waste products like urea and excess salts. Feces, on the other hand, consist of undigested food, bacteria, and other waste materials that were not absorbed by the body during the digestion process.
