What has a tube containing cells with cilia?

A tube containing cells with cilia is typically referred to as a ciliated epithelium, which is found in various parts of the body, including the respiratory tract. The cilia are tiny hair-like structures that help move mucus and trapped particles out of the airways, aiding in cleaning and protecting the respiratory system. This type of epithelial tissue plays a crucial role in maintaining respiratory health by facilitating the clearance of debris and pathogens.
