Magma chamber underneath, then the pipe and finally the crater for the lava to flow from.

I'd heard it was a chimney, Teach. Seems someone else thinks so, too.

"This primary magma is hotter and lighter than the surrounding material, ascending to the surface and stops into a point called magma chimney, a gathering location of the network of tunnels through which it has advanced till then."

Correct term is vent.

Vent: The opening at the earth's surface through which volcanic materials issue forth

Pipe: A vertical conduit through the Earth's crust below a volcano, through which magmatic materials have passed. Commonly filled with volcanic breccia and fragments of older rock
