What is a chamber in a pyramid called?

A chamber in a pyramid is typically referred to as a "tomb" or "burial chamber." In ancient Egyptian pyramids, these chambers were designed to house the deceased and their burial goods. The most famous burial chamber is found in the Great Pyramid of Giza, which contains the sarcophagus of Pharaoh Khufu. These chambers were often located deep within the pyramid to protect the body from theft and disturbance.
