air shafts were necessary (even though the dead pharaoh was already dead and not breathing) because..?

For Construction of the Pyramids

Explanation:

Explaination 2- Some experts believe that they were built to provide ventilation for the people working inside the pyramid while it was being built. Other experts believe that these shafts had a religious purpose because they are directed towards certain stars. This air shaft is directed towards the northern polar stars.
