If light is produced by the release of photons when electrons return to stable energy levels, why do blackbody objects emit light over a continuous and wide spectrum?

Doing some light reading on the Internet and was reading up on black body objects and why objects glow when they heat. I was told that photons are released through the excitement of electrons, and then you have things with emission spectrums and so on. This implies that the spectrum should only have very specific wavelengths of light. However, I have looked at spectrum graphs of objects such as incandescent lightbulbs and found that they emit light over a continuous spectrum of various intensities that extend over a significant range of wavelengths. 

Why is this so? Why are the emission spectrum wavelengths not emitted? What is it in the function of blackbody objects that make them emit light across a constant stream of wavelengths?

Charged particles emit a (quasi-)discrete spectrum of EM radiation when they transition between *bound* states, but they can also emit continuous spectra when they transition between *scattering* states.

This is what bremsstrahlung is, and that's ultimately what causes the continuous Planck spectrum of a black body.
