It's supporting the external wall.

You can tell the direction of the floor joists by the nail positions in the flooring.
If you have floor boards and not chipboard the joists run the opposite way to the boards.

PS. The shortest direction for the floor joists in your plan is across the dining room.
ie. bearing on those internal walls.
