Some of you seem to have some background in general systems theory, I admitt a general lacking in biology and general systems theory, but, if you are to contend that, there is not consciousness behind this contruction of a multicellular body and its maintenance you will have to invest some time here to explain how this comes about.
In my own case I'm a physician and medical researcher, so I don't look at this from the perspective of systems theory -- and if systems theory regards consciousness as simply chemical / energetic responsiveness to external stimuli, then that is very much different than consciousness from a biological perspective.
From the point of view of plain old biology and medicine, consciousness is a function that is produced by an underlying mechanism, specifically the brain of an animal under conditions of wakefulness. A plant can be said to be aware of moisture in the soil and the direction of sunlight in the sky -- but this is not sensed or appreciated centrally
-- so a plant cannot be said to be conscious. Our hair follicles tense up and produce goose bumps when we're cold -- this is an involuntary effect of our efferent central nervous system -- but that does not mean that our hair follicles are conscious
of cold -- they're just responding to a biological mechanism. Our consciousness does not pertain to everything in our body -- only the things we're aware of.
How does consciousness come about? Well, digestion is produced by the physiologic functions of the stomach, ambulation is produced by the physiologic functions of the legs, hemofiltration is produced by the physiologic functions of the kidneys, and consciousness is one (of many) physiologic functions produced by the brain. And these physiologic functions inhere in the anatomy, physiology, histology, cell biology, and genetic and epigenetic processes of that organ (as well as all the other afferent neurological and endocrine/paracrine communication mechanisms that make it responsive to other parts of the body).
