Quizplus · Accepted Answer

Primary functions of the GI tract include the breakdown of food particles into molecular form for digestion; the absorption into the bloodstream of small nutrient molecules produced by digestion; and the elimination of undigested unabsorbed food stuffs and other waste products. Nutrients must be broken down into molecular form, not cell form. Fluid, electrolyte, and acid-base balance are primarily under the control of the kidneys.
