absorbed through the wall of the large intestine?

'The intestinal epithelium and the normal intestinal microflora represent
a barrier to the movement of pathogenic bacteria, antigens and other
noxious substances from the gut lumen. Under normal circumstances
this barrier is intact and provides normal intestinal function. When either
the epithelial cells or the normal microflora are disturbed altered
permeability facilitates the invasion of pathogens, foreign antigens and
other harmful substances. '
