muscles of the small intestine continually churn the food, in order to both
liquefy and expose all the contents to the villi. Addition of bile from the
liver breaks down the large molecules of fats and most proteins in order for
them to be small enough for absorption. Secretions from the pancreas assist in
breaking down carbohydrates (sugars). High fiber content in the intestinal
tract, helps reduce the fat absorption and instead carries it out to
elimination.
Not everyone consumes a balanced diet of fiber, etc, and in many people pockets
of undigested or partially digested food accumulates in "pockets" where it will
then ferment. (Ever have gas?) If that particular part of the content contains
certain kinds of bacteria, then toxins are produced causing illness such as
fever, diaherrea, etc.
Sorry this is so disjointed, my memory is somewhat flat on all the details of
digestion, metabolism and the ever famous Krebs cycle. Those classes were many
years ago.

Subject: Digestion Question
: Hey guys, i remember being tuaght in school that the body absorbs nutriets
from the food through the "villis" that are inside one of the intestines. What
i wonder is, does it absorb all the nutrients?? since it's only brushing
against the surface of the "food", how can it get everything?
