An undigested substance in the alimentary canal is typically referred to as "indigestible material." This can include things like fiber, which humans lack the enzymes necessary to break down completely. Other examples of indigestible material include certain types of carbohydrates, such as resistant starches, and substances like cellulose found in plant cell walls.
Indigestible material plays an important role in the digestive process, as it helps to regulate the passage of food through the digestive tract and provides bulk to stool. Additionally, certain types of indigestible material can serve as a food source for the beneficial bacteria that reside in the gut, helping to promote a healthy digestive system.
