There is a big difference between external and internal respiration. External respiration is basically the transfer of gas between respiratory organs such as lungs and the outer environment. It takes place prior to internal respiration. Internal respiration is the transfer of gas between the blood and cells.
Whatever happened to Julian Lennon? After seven years away from the limelight - a time spent getting his life back together after a disillusioning experience with pop stardom' - the son of a beloved rock icon returns to the public eye and ear with his own record label and a new album, Photograph Smile.
John Lennon was killed by Mark David Chapman. The reason is unclear and seems to have changed a bit over the years, although it could be simplified by saying that he was insane. At his previous hearing in 2012, Chapman described how Lennon had agreed to autograph an album cover for him earlier on the day of the killing.
