The quick answer is that the engines on the airplane is design to push air straight backwards this makes the airplane accelerate straight forward.
When the airplane wants to lift whe have to get a force that pushes it upwards(or else it would not lift).
The upwards force comes from two major sources, by the air pushed down by the wings(which also are pointing upwards and therefor pushes down the air that passes under them) and by the engine that is pointing downwards.
