Distinguish between a vent and a pipe in composite volcano?

In a composite volcano, a vent is the opening through which magma, gases, and volcanic materials are expelled during an eruption. Vents can vary in size and may be located at the summit or along the flanks of the volcano. In contrast, a pipe, or volcanic pipe, is a vertical conduit that connects the magma chamber beneath the volcano to the surface, allowing magma to rise and eventually reach the vent. Essentially, the pipe serves as the pathway for magma, while the vent is the exit point for volcanic materials.
