A breathing lung live on stage…
Check out this entertaining TEDMED 2010 Talk in which Shaf Keshavjee brings a breathing lung onto stage and explains how the process of transplantation works. Plenty of links to the human health and physiology topics here:
Early in the talk he refers to Charity Tilleman-Dick, an opera singer who can sing again after a double lung transplant! It’s also funny to see Martha Stewart get on like a high-schooler with her camera-phone.
Fore more excellent anatomy and physiology resources, GetBodySmart is a great website.
