The consecrated Host has no physiological functions. For instance It has no respiratory reflexes, It has no circulatory system, It has no musculature. But it is Christ's real, substantial Body under the appearance (and that would include the chemical analysis) of bread.
Maybe you didn't know that.
This is something made up by your religion, isn't it??? 'Flesh and blood in the real substantial sense'...Oh brother!!! That's got to be something to dupe poor Catholics who ask too many questions...

Of course flesh has no functions if it is not part of an organ...And if it has none of those things you mentioned, it is NOT flesh and blood...
Jesus had real flesh and blood...Your religion's claim is that it eats THAT flesh and blood...Real flesh and blood with real DNA...If it has no DNA, it is not the flesh and blood of Jesus...You need to find another name for it...
