stomach is where the pancreas, a gland organ, can be
found. It manufactures a mixture of enzymes that are sent
to the duodenum. The gallbladder is also connected to the
duodenum by a duct. It’s a pear-shaped sac that discharges
a green-brown waste product collected from the liver called
bile. It contains acids that break down fatty matter.
The liver performs hundreds of different functions. It’s the
body's main chemical factory. Nutrients released into the
blood by the small intestine are processed by the liver.
This creates energy-giving glycogen from carbohydrates
and converts dietary proteins into the kind of proteins our
blood needs. Any essential vitamins and minerals, along with
these proteins, are then stored or released as needed. Any
unwanted chemicals, i.e.any alcohol consumed,are broken
down by the liver, detoxified and passed from the body
as waste.
