This is another but simpler and easier to understand explanation of the system used in the McLaren MP4-25 regarding the rear wing and the ability for the drivers to control the amount of airflow to it during a race.

"It is believed that a small air scoop in the nose of the car — you can see it just below the steering wheel in the pic below — allows air to enter a tube that runs through the cockpit and the air intake above the driver’s head to the rear wing. From there it flows to the wing and passes through small slots to the back side of the wing, where the added energy can aid the airflow like the slats on a plane. This increases downforce in the corners.
