Digestive System
Infections
- The digestive system is often divided
into two sections: gastrointestinal (GI)
system is the tubular path from the mouth to
the anus.
- The second section is referred to as the
accessory digestive organs. The accessory
digestive organs are responsible for either
grinding the food (teeth) or injecting
digestive secretions (pancreas).
- The internal surface of the small
intestine has millions of hair like
projections called villi.
- Intestinal peristalsis moves undigested
and unabsorbed food from the small intestine
into the large intestine and colon.
- The colon finishes the absorption of
nutrients and water.
- Feces is the remaining undigested
material which is eliminated via the anus.
As much as 40% of the fecal volume is
bacteria.
- Antigenic drift and antigenic shift
primary mechanism for production of new
strains of flu.
- The membrane covering most of the GI
tract and protects it is called the
peritoneum.
- Accessory digestive organs include
tongue, teeth, liver, gallbladder and
pancreas.
- The esophagus, stomach and small
intestine (duodenum) are almost free of
microbes.
- Gastroenteritis is an inflammation or
irritation of the lining in the: stomach or
intestines.
- Bacteria growing on the tooth�s surface
make acid which then destroys the enamel.
- Gingivitis is an inflammation of the
gums surrounding the teeth.
- Bacterial gastroenteritis is an
inflammation of the stomach and intestines
caused by bacteria or bacterial toxins.
- Bacterial pathogens of the
gastrointestinal tract, attach and bind to
the surface, proliferate and transmit
disease. These microbes develop mechanisms
that optimize these characteristics while
minimizing the host�s ability to destroy
them.
- Viral gastroenteritis is an intestinal
infection caused by several different
viruses.
- Hand washing is the single most
important way to avoid infection of the
digestive system
- Fecal Oral route is a major cause of
digestive diseases due to infection.
- The human heart is a muscle with four
chambers.
