What is the purpose of the vents in Egyptian pyramids?

The vents in Egyptian pyramids, often referred to as "air shafts," served both practical and symbolic purposes. They were designed to facilitate the ventilation of the burial chambers, allowing for air circulation and reducing moisture that could damage the tomb. Additionally, these shafts may have had a ceremonial function, aligning with specific stars or celestial bodies, reflecting the ancient Egyptians' beliefs in the afterlife and their connection to the cosmos.
