acini, in the pancreas receive stimuli from the nervous system and be-

gin producing pancreatic juice. However, the pancreas does not start
working at full capacity until your food actually passes through the
duodenum doorway. The more food arrives, the more enzyme that is
secreted.
The pancreas can also distinguish between the kinds of food we
consume, and secretes different enzymes accordingly. For example,
when you eat foods such as pasta or bread that are rich in carbohy-
drates, the pancreas secretes mainly a carbohydrate-digesting enzyme
called amylase. 64
This mechanism is exceedingly sensitive, because enzymes must

not be wasted, and at the same time, the intestine must not accidental-
ly digest its own walls. This entire system must produce adequate en-
zymes to keep a living body alive. Were this process under our con-
scious control, we would spend all our time calculating when, which,
and how many enzymes needed to be produced and pondering about
to make use of them. However, their production and operation are ac-
tually beyond our control and knowledge. Other structures—again
consisting of fat and proteins—are charged with controlling enzyme
production. Hormones specially manufactured in the intestinal wall,
secretin and pancreozymin, take on the job of stimulating enzyme pro-
duction. The hormone secretin stimulates the pancreas into secreting
pancreatic juice, rich in the sodium bicarbonate that neutralizes acid.

The hormone pancreozymin stimulates the production of enzymes by
the pancreas.
When food passes from the stomach to the duodenum, secretin
and pancreozymin are released into the bloodstream. Thanks to these
hormones, the duodenum is protected from the destructive effects of
hydrochloric acid. By way of the bloodstream, secretin and pancre-
ozymin reach the pancreas and signal it to produce sufficient quantities
of fluid rich in water, bicarbonate and digestive enzymes, which will
