You are asking questions similar to as I was asking about biochemestry etc. just by one point reading. Better you study the whole system in full. However I inform you about tissue salts:-
Please explain why homeopaths believe: "Our body contains twelve inorganic elements."
These are twelve major tissue salts (not elements) found on analysis of human ash.
From one of your links. If they are referring to biochemistry, and more specifically the periodic table of elements, then the body, by direct examination for elemental analysis even in the blood has many more than just 12 inorganic elements. The blood contains the usual CHOPSN, but it also has calcium, mercury, iron, gold, silver, zinc, argon, copper, and many more trace elements and minerals. This is clearly wrong from a biochemical standpoint. Can you defend this belief with any elemental analysis data?
If you see the chemical composition of human's body, total nos of elements covered by these 12 tissue salts will be about 97% of all elements in percentage of their presence. It may mean that these may be capable of handling 97% of our functional problems & balance 3% could be possible by itself if 97% is covered (although 97% is also a prominent figure). In some other later books about 40 tissue salts are covered ( almost all elements). However, in 12 tissue salts, I am bit trying to find-- why Nitrogen is not given importance as not there no where.
HS may clarify your 2nd point in a better way. However there is substancial influence & terminologies of allopathy in homeopathy because introducers & pursuers of homeopathy were mostly MD level doctors.
