A door could be an opening/closing structure used to block off an entrance, typically consisting of an interior side that faces the inside of a space and an exterior side that faces the outside of that space.
When open, doors could admit people, animals, ventilation, and light. The door can be used to control the physical atmosphere within a space by enclosing the air drafts, so that interiors may be more effectively heated or cooled. Doors might be significant in preventing the spread of fire. They may act as a barrier to noise. Many doors could be equipped with locking mechanisms to allow entrance to certain people and keep out others.
