What thickens the fluid in the intestines?

The fluid in the intestines is thickened primarily by the absorption of water and electrolytes, which occurs mainly in the large intestine. Additionally, mucus secreted by intestinal goblet cells also contributes to the thickness of intestinal contents, aiding in lubrication and the formation of stool. Dietary fibers can also play a role by absorbing water and increasing the bulk of the intestinal contents, thus influencing the consistency of the fluid.
