where did the first blood transfusion take place
Blood transfusion Working at the Royal Society in the 1660s, the physician Richard Lower began examining the effects of changes in blood volume on circulatory function and developed methods for cross-circulatory study in animals, obviating clotting by closed arteriovenous connections. The new instruments he was able to devise enabled him to perform the first reliably documented successful transfusion of blood in front of his distinguished colleagues from the Royal Society.
Blood In Blood Out The film was shot in and around Los Angeles and East Los Angeles and inside the walls of San Quentin State Prison. The main character Miklo is sent to San Quentin, where much of the film's plot takes place. Several of the then-inmates appear in the film as extras. In addition, several of the prison staff members also appear as others and some facilitated the production of the film by serving as technical advisors. Many members of the staff were given small lines in the film, with the warden giving an extended cameo in a part that is somewhat integral to the plot. In addition, actor Danny Trejo, who appears in the film as Geronimo, had served time in San Quentin before deciding to become an actor.
