dead skin

Q:

1. Does skin, flesh and teeth become najis when removed from a living human?

2. Must the skin, flesh, and teeth of a living human be buried when removed from the body? For example, when some flesh gets cut off in an injury. Or when a child loses one of his milk teeth.

3. Is it permissible to throw away bloody plasters, tissues, and bandages etc. in the bin?

Q: Please can you advise if a bed sheet with stains (possibly not najis, possibly sweat or drooling saliva) has been washed in the washing machine with other stuff but the stain has not been removed fully then is the sheet as well as other stuff rendered impure even after 5 rinses and spins or is it paak. Also is raw fleshy skin due to a burn peeling off on the arm considered pure?
