Does anyone know whether the triangular shaped inlets on the underbelly of all 747s serve a purpose?

They serve a purpose? I thought they looked pretty. Is that not a good enough reason these days?
|Quoting OzLAME (Reply 9):|
These inlets are not quite triangular, they are more a sort of teardrop shape that has the bottom cut off. The generic name for inlets of this shape is NACA Duct, after the National Advisory Commitee for Aeronautics (forerunner to NASA) that came up with the shape.
