It is called a vent.
Magma is lava before it actually reaches the surface of the Earth. So magma comes from a volcano, not lava.
lava
Magma that flows onto the Earth's surface is called Lava.
When lava comes out the side of the volcano, it is called a lava flow or lava eruption. This can happen as a result of pressure build-up within the volcano causing the lava to find alternative pathways to reach the surface, often leading to lava flowing out from the sides.
A volcano is the opening in the crust through which lava comes forth.

hot burning lava comes out of an volcano when it explodes
Molten rock (magma) that spews from a volcano is called lava, When it cools, the lava forms igneous rocks.
Magma that reaches the surface it is called lava.Molten rock from the Earth's interior that breaks through to the surface is called lava
Lava comes out of a volcano through volcanic eruptions. When pressure builds up underneath the Earth's surface, it forces magma to rise to the surface and flow out as lava. This molten rock can flow out through cracks in the Earth's crust, known as fissures, or through the main vent of the volcano.
