The Large Intestines main function is to receive food and fluids from the Small Intestine, re-absorb some of the fluids then excrete the remainder as feces.
Many functions attributed to the Small Intestine in Western bio-medicine are attributed to the Spleen in Chinese medicine.
The Spleen controls the transformation/transportation of food and fluids throughout the digestive system, including Small and Large Intestine.
Hence signs such as diarrhea, abdominal distention and discomfort usually listed as Spleen imbalance (Deficient Spleen Qi or Yang).
