The Chinese word 内脏 (nèizàng), meaning "internal organs", is a compound noun formed by combining two characters: 内 (nèi), which means "inside" or "internal", and 脏 (zàng), a simplified form of 臟, which specifically means "organ" or "viscera". This construction follows a common modifier-head structure in Chinese, where the first character 内 describes the location or category, and the second character 脏 provides the core subject, together creating a precise term for the organs contained within the body's cavities.
