I think he has his Left upper lobe but it is smaller Curt...don't know why it would be unless it was a birth defect of some sort or perhaps just a weird change due to other injuries within the abdomen or chest wall that would have kept the left upper lobe from growing to it's normal size. Either way it is interesting...now you'll have me doing more work during field dressing  

I did not know such things.Very interesting...
Does anyone have an idea about the deer with the arrow in his lungs and did not die quickly.

Good Shooting.........

It's almost as if not only is the left lung very undersized up front(1st pic), but the right lung seems to be a bit bigger than normal up front(2nd pic)??

Curt did you cut into the lungs? Are there any masses or tumors? does the collapsed lobe  internally look like the other areas of the lung?
