The Chinese term '五脏六腑' is formed by directly combining the numeral '五' (five) with '脏' (referring to the solid organs: heart, liver, spleen, lungs, and kidneys) and the numeral '六' (six) with '腑' (referring to the hollow organs: gallbladder, stomach, large intestine, small intestine, bladder, and triple burner), creating a compound phrase that enumerates the complete set of vital internal organs as defined in traditional Chinese medicine.
