The ball-point pen has a hollow body in which an ink-refill is inserted. The refill has a thick ink and so it doesn't leak like a fountain pen. The part of the refill that writes has a tiny metallic ball, which is partially outside the refill body and partially in contact with the thick ink.
It is to this ball that the ball-point pen owes its name.
When the pen moves across the surface of a paper, the ball rotates. In the process, the side of the ball which is in contact with the ink touches the paper, leaving the ink mark. As the pen slides over the paper the ball keeps rotating, bringing the ink to the surface and enabling you to write

They're called "ball-point" pens because they have a small ball at the tip to control the flow of ink.

because they actually have a small metal ball at the tip that moves around to distribute the ink so you can write. look at one and see.

Because the tip is like a ball. What's even more ironic is the fact that they are available in blue.

at the tip of a ball pen, if you look closely there is a ball there. and when you write the ink flows out of the ball.
