Oh, about the cadavers. I have assisted with organ procurements, where surgeons remove donated organs from freshly deceased individuals. It is extremely educational to see the internal organs and exactly where they lie, etc. Usually they take all the long bones (femur, tibia & fibula), and the heart. Obviously the heart is not beating, so they don't use it for heart transplants. They mainly salvage the valves, which are still useful many hours after death. They eventually extract the marrow from the bones, which I believe is used for cancer patients. In the procurements I've assisted in, the long bones of the legs were replaced with CPVC piping (the same type of rigid, white pipe found in homes) to give them rigidity for processing by the funeral home, etc.
When we bring in a patient that doesn't survive, and we need certification or practice with a certain procedure, we will ask the ER physician, who will in turn request permission from the family for minor, semi-invasive procedures to be performed on the cadaver. Generally we practice things like intubation, cryco-thyroid punctures (placing a large-bore IV catheter through the trachea to allow a patient to breath if they have an airway obstruction, or their trachea has swollen shut from severe allergic reaction or from fire / smoke inhalation), needle chest decompression (placing a large-bore catheter in the intercostal space between two ribs to allow air / blood to drain from between the lungs and the rib cage), and placing an IV catheter in the left or right jugular vein of the neck.
