This is the description for the conduit of a volcano. Use the link below for more information, including a diagram.Dont listen to that because that's not true its the pipe and if it's not that then its the vent:)
the opening where the lava flows is call a vent
The magma (lava) chamber goes up a conduit (pipe) until it hits the throat (top) of the volcano. In which the lava comes out the vent. Lava can also come out of a branch pipe off the conduit. Lava can come off a side vent. Depending on what type of volcano it is. The top of the volcano can leave different sizes of craters.
A Magma Chamber is a space (that can change size) at a depth below a volcano in which magma can accumulate prior to an eruption. A volcanic vent is a conduit connecting the magma chamber to the surface. It is though this that the magma flows during an eruption.
