Now, we also have a lower lobe, also known as our inferior lobe. And this is separated by a line called the right oblique fissure because it's also slanted, just like this one. So we have the upper, the middle and the lower lobe. Now, superior simply means it's found above, and inferior means it's found below. And that's exactly why these two are referred to as a superior and these two lobes are referred to as our inferior lobes. So we see that our two lungs are found within our thorax, within our thoracic cavity, and below our lungs.
