A crater is a bowl shaped area at the top of the volcano around the central vent where magma comes out. Magma is beneath the volcano. Lava is the name of magma after it leaves a volcano.

The magma moves upward through a pipe, witch is a long tube that connects the magma chamber to the surface.Molten rocks and gas through it's opening called a vent.It's all written here in a text book called Prentice Hall Earth Science.
