Vents in the volcano are passage ways for the magma, steam, and heat to escape the earth.
The channel that magma uses to travel toward the vent in a volcano is called a "conduit." It is a narrow passage within the volcano that allows molten rock to move from the magma chamber to the surface during an eruption.
A Magma Conduit is hot fluid or semi-fluid material within the earth's crust from which lava and other igneous rock is formed by cooling.
The order of parts through which magma reaches the surface of a volcano is the magma chamber where it accumulates, followed by the central vent or conduit where it travels upwards, and finally the crater or vent at the surface where it erupts and flows out as lava.
The amount of viscosity present in magma depends on the amount of silica it has. A composite volcano produces rhyolitic lava which is very thick. A shield volcano produces a basaltic lava with less silica and significantly less viscosity.
It's called a conduit.

It was the middle leg of the triangular trade route that Europeans followed.

A magma is injected into a volcano's plumbing the first thing you see is inflation of the land/volcano surface, this would be accompanied by earthquakes and low frequency harmonic sounds caused by the flow of magma through the volcano's passages (like a flute). There would then be the release of gasses from the vent (a phreatic eruption) as magma heats ground or surface water. This may then be followed by eruption of magma from the volcano's vent.
They follows the northwest passage to get to the present day.
