Their physiological function is "transmission", and their physiological characteristics are "diarrhea without hiding" and "solidity without satisfaction". Food and drink enter the stomach through the esophagus, decompose in the stomach, pass down to the small intestine, and secrete turbid gas through the differentiation of the small intestine. Its subtlety and body fluid are absorbed by the spleen, transferred to the lungs and spread all over the body to meet the needs of life activities of zang-fu organs and meridians.
Its turbid residue is released into the large intestine, and through the conduction of the large intestine, it forms stool and is excreted; The waste liquid is gasified by the kidney to form urine, which seeps into the bladder and is excreted.
