Why tungsten as used in bulbs in that place? Why not other elements?

Tungsten can heat up to white hot state and this produces light as well as it increases the resistance of tungsten too. Therefore it is used in incandescent bulbs.

When electric bulb gets high electricity the tungsten metal melts and causes bulb to fuse. This prevents the bulb from further damage.

Filaments in incandescent light bulbs are made of tungsten. When electric current goes through the filament, the filament glows. It may also be known as the electron emitting element in a vacuum tube. To make the bulb produce more light, the filament is usually made of coils of fine wire, also known as the coiled coil.

Tungsten has high melting point - 3380 C. Tungsten is used as it will help to emit more light as it has less resistance.
