The spleen meridian The spleen is located in abdominal cavity. TCM regards the spleen and stomach as the "acquired foundation of life." Its main physiological functions are governing transportation and transformation of nutrient essence and body fluid, controlling blood flow and supporting the muscles and four limbs. The mouth and lips are important to check externally to know how the spleen is functioning. The spleen meridian communicates with the stomach meridian creating an exterior and interior relationship. These two organs influence each other closely.
