Intestinal juice is the watery fluid secreted by the glands lining the small intestine. It contains enzymes that help break down food molecules into smaller, absorbable units. Think of it as the final stage of digestion in the small intestine. It assists in further breaking down chyme (partially digested food). It is crucial for absorbing nutrients into the bloodstream. Without it, your body wouldn't be able to get the energy it needs from food.
