On Starfleet vessels, Jefferies tubes are internal maintenance conduits that are used to provide crew access to various ship's systems. In emergencies they're also used for moving around the ship if turbolifts are not functional. Doors within the Jefferies tubes can be sealed for safety or security reasons.
