Does fibre really speed up you're bowel system?

Do foods high in fiber really speed up the bowel system just as much as spoon of pro laxative would. Figs and Prunes seem to do the job more than laxative's such as califig. What works most for you? lmao gross question I no but just be mature, we are adults/young adults not kids :-) soo yeahh thanks for the replies I get to this question.
