It travels through a "Pipe" and explodes out the "Vent", or possibly the "Side Vent", and another world for the hole at the top is the Crater.
The tunnel through which lava travels to reach the surface of a volcano is called a volcanic conduit. It is a passage that connects the magma chamber below the volcano to the vent at the surface. The lava moves through this conduit under pressure before erupting onto the surface.
The solidified lava forming the walls of the lava tube will act to insulate the molten lava. It will therefore cool more slowly than lava at the surface and so will have a lower viscosity (it will be more runny) and so will flow faster than lava at the surface.
A lava flow is basically a stream of lava on the surface. A lava tube is an underground cave through which lava flows downhill. A lava fountain is lava shooting into the air out of a volcano in much the same manner as a water fountain.
As magma rises through the Earth's crust, it can carve into a tube-shaped structure known as a lava tube. This occurs when the outer surface of the flowing lava cools and solidifies while the molten lava continues to flow beneath it, creating a hollow channel. Over time, as the eruption ceases and the lava drains away, these tubes can remain as natural conduits. Lava tubes are often found in volcanic regions and can vary in size and complexity.
Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.
The phenomenon is called lava tube formation, where molten lava flows through a natural tunnel-like structure underground. Lava travels through these tubes, allowing it to move further away from the volcanic vent.

The tube through which sperm travels is called the vas deferens.

The solidified lava forming the walls of the lava tube will act to insulate the molten lava. It will therefore cool more slowly than lava at the surface and so will have a lower viscosity (it will be more runny) and so will flow faster than lava at the surface.
The tube that the egg passes through is called the fallopian tube. It is where fertilization typically occurs, as the egg travels from the ovary to the uterus.
Can be veins, can be arteries, can be capillaries, can be the aorta..
Urine travels through the urethra to leave the body. The urethra connects the bladder to the exterior of the body.
A lava tube cave is a natural tunnel formed by the flow of lava, creating a channel for molten lava to move through during a volcanic eruption. When the lava flow stops, the tube can cool, leaving behind a cave-like structure with unique geological features.
