Irena Gut Opdyke was 81 through 85 when she died
fibre helps the feces to form bolus. Fibre is not at all digested in the gut. It moves all the way through the gut sticking to the feces and makes it bolus for easy passage.
The gut is where food is digested, nutrients are absorbed into the bloodstream, and indigestible waste moves through and leaves the body.
fud makes it digeste throught the gut
Nutrients leave the gut and enter the bloodstream through the lining of the small intestine.

An incomplete gut only has 1 opening. Basically if something has an incomplete gut, it has no anus, and all food that it takes in must either be completely digested, or re-excreted through the mouth.
Fiber.
