To blow heated or cooled air into the house... you usually see floor vents on houses w/ a crawlspace underneath or those w/ little or no attic, or older homes that have been retrofitted w/ a HVAC system.

That is where your heat from your furnace and cold air from your air conditioner enters your room.
