Deer Anatomy - YouTube Watched this video last night and thought it was worthy to pass along. This guy has spent a long time researching the data he presents. There are several videos in the series. The video where he uses an air compressor to re-inflate the real lungs of a deer is absolutely fascinating. Hope you folks enjoy and share the information. It certainly opened my eyes to some interesting aspects of what your arrow does when it enters a deer's body. Smitty
