In brief: Fiber is good 4 you

Fiber, of both water soluble and water insoluble variety, provides health benefits.
Fiber accelerates how quickly food transits through the gut. Fiber adds bulk to stool and improves bowel regularity. Fiber can be used as an adjunct to weight loss by filling you up without excess calories, and in so doing restricting fat intake. But too much fiber can make you gassy and increase stool volume.

Water soluble fiber can also help lower blood levels of cholesterol by binding cholesterol in the gut.
Dr. Charles Cattano
Per Harvard Health Letter, 9/2011 and Mensa Bulletin, 12/2011: Fiber helps against respiratory problems, infections, strokes, and heart attacks by blocking absorption of cholesterol and sugar. Anti-inflammatory abilities of fiber may account for other health benefits. Raw fruits and vegetables are the very best sources of fiber. Juice is only half as good as whole fruit for this purpose.

In brief: See below

soluble fiber can slow down the stool transit and absorb water in the case of loose stools or diarrhea.
Insoluble fiber, which is not digested well, increases the bulk of the stool as well as the transit time and helps in people with constipation and diverticular disease.

In brief: Feed the colon

The cells lining the colon obtain much of their nutrition from the break down of fiber.
A short answer to some fairly complex processes.
