And for our scientific consideration in this approach, we decide to postpone the acknowledgement of any of those orientations terminations, and spot our focus on all bio-integrative entities with their functional and structural facts, which is prior for us among our studies for human body as a multicellular organism. 

When we look at any multicellular organism known, we notice many features that characterize them apart from any other known existed unicellular or cell-free entity.../ to be continued
