Aluminium corrosion resistance. Aluminium corrosion resistance is very good in untreated aluminium. Untreated aluminium has very good corrosion resistance in most environments. This is primarily because aluminium spontaneously forms a thin but effective oxide layer that prevents further oxidation.
Human body is just the medium for soul to survive on earth. Soul wears human body for its learning on earth. Soul can not experience feelings in its original form and therefore it needs a human body. Now when a human body dies, a soul leaves that body and return to its original form. Sometimes, in case of sudden accident, a person dies and soul returns to its original form.
I'm taking this to mean that you'd die if you were missing these organs. You can live without some organs like the gall bladder, appendix, tonsils -- commonly removed without a person dying from it. And you can live without some organs by having a mechanical or artificial way to make up for them like having dialysis for missing kidney function, artificial heart, ..
