The small intestine rules "containing and transforming." It receives what the stomach has not completely digested and this material is further digested into nutrients. The small intestine also separates the "pure" from the "impure." Like the stomach, the small intestine sends the "pure" (useful) part to the spleen where the nutrients will be distributed, and the "impure" (waste) part is directed down into the large intestine. Any useless water produced in the digestion process will be sent to the bladder and stored as urine. Healthy small intestine functions are essential for normal urination and defecation. If disharmony is present, an individual may experience dysuria (difficulty or pain on urination) or loose stools.
