Major organs and intestines involved
in the human digestive system.
of the digestive system, obviously enough, is to break down
food into small enough parts for the body to extract vital
the way it actually works is an amazing feat which is accomplished
by several organs, all working in sync to absorb vital ingredients
we need, and to excrete the rest as solid waste (or as liquid
waste by the urinary
Digestion starts in the mouth, where our teeth break food
down in to more manageable chunks.
food passes down the esophagus and into the stomach, where
it is exposed to stomach acid and broken down further.
From the stomach, food enters the small intestine, where food
mixes with a wide variety of digestive juices to be gradually
broken down and absorbed by the body.
the liver is responsible for
producing another digestive juice bile which
is stored in the gallbladder, located just behind the liver.
At mealtime, bile is squeezed out of the gallbladder through
the bile ducts and into the intestine to mix with the fat
in food to dissolve it.
this "fat free" mixture is further broken down by
pancreatic enzymes, and moves on to the
large intestine, where food that could not be absorbed by
the body waits to be excreted as feces.

is a fairly sensitive organ and sometimes liable to upset,
for instance which is not only annoying but, especially if
chronic, a potential source of more serious health problems
later in life. Adequate chewing makes the stomach's job easier,
and will relieve any undue stress that the stomach might experience
trying to break down large chunks of food.
intestine may also be effected by poor digestion, and a resulting
condition known as diverticulitis,
whereby small food particles get lodged in the intestine walls
and cause infection. However, adequate fiber and liquids in
the diet will go a long way towards keeping them working smoothly.
Staying away from junk foods will also help avoid problems
that arise when the gallbladder has to work overtime to process
a diet high in fat.
