From the perspective of Zangxiang， the concept of "the heart governing the mind" focuses on the functional attributes of the heart， while "the heart governing the blood vessels" focuses on its anatomical attributes. In essence， the heart in traditional Chinese medicine represents an integrated system that combines both functional and anatomical aspects. To elaborate， the anatomical heart"system includes the heart， stomach （including other digestive organs） and brain， which serve as the material base of the spirit. And the functional heart system includes the brain and stomach （as well as other digestive organs like the gallbladder）， which manifest the function of the spirit. Anyway， considering all aspects， the brain serves as the ultimate conductor of internal organs that actually govern the mind， which is "single-minded".
