12. Medical science does not include the human mind as a "system" of the body, but without it how do the other 11 systems function? The brain is listed as part of the Nervous system, however, as the brain is physical, the mind is spiritual. Without the spiritual component, human beings would be no different than plants or animals.
The mind is the set of thinking faculties including cognitive aspects such as consciousness, imagination, perception, thinking, judgement, language and memory, as well as non-cognitive aspects such as emotion.
With these twelve systems in the human body, how is it that Big Phama can come up with thousands of "medicines" for only twelve systems? Some drugs are necessary to stabilize a patient, but no one should be on multiple meds for life.
