Well this is true.However,the term "Belly" would seem to refer to the outer appearance of the body,even I would go so far as Carapice,were you to be referring to an invertebrate.The "belly" in a fairly strict sense,is the portion of the body that houses(or in some cases-"Holds in") those organs beneath the chestal area forming the abdomen and it is these organs,namely the duodenum,that would most likely to arouse in one the feeling of discomfort to do with food consumption.
One of the reasons for this,and by no means the only reason,is that during the process of breaking down food into nutrients,the brunner glands release or secrete alkaline mucci in support of the work carried out by the intestinal enzymes.Further aiding this vital work,the pancreatic duct adds bile to the heady mix,whose primary function is to absorb fats,along with its own enzymes which again help to break down food.One of the primary functions of the duodenum is to secrete hormones which in turn trigger the release from the pancreatic duct of pancreatic juice and of course,bile.
In another part of this process,namely the passage of foodstuffs from the duodenum to the jejunum,which is lower in the abdominal cavity,those same alkaline fluids from the brunners glands help to neutralise a product known as Chyme,which is ever present in the stomach and takes the form of an acidic substance.This has the effect of protecting the jejunum,which has a lower tolerance for the acidity of chyme.
It is this that I believe to be the cause of my discomfiture,rather than anything to do with the "belly" par se.As a matter of record I of course do not posess a belly of any great significance.
The processes described are of course all intestinular as oppposed to boneular,which would have more to do with structure as opposed to content.
Again I feel drawn to point out yet another golfing reference,lest any unkind soul would dare to suppose we were heading off piste(or topic) and that is to mention the "belly" putter,designed to be operated using the belly,or abdomen as a fulcrum for the club.A belly Putter is typically longer than a regular putter,and both are probably higher off the ground than I.
