The Digestive System
By Sarah C.
The Mouth

The mouth is where the digestive
system starts. The mouth chews your
food and transfers it to the next part
of your body
Esophagus

The esophagus conveys boluses of
food from the pharynx. The esophagus
is routinely exposed to rough and
abrasive foodsuffs.
The Stomach

The stomach is a muscular organ on
the left side of the upper abdomen.
The stomach secrets acid and
enzymes.
The Liver

The liver cleans your blood, it
produces bile, and it stores glycogen.
Large intestine

The large intestine consists of the
cecum and colon.
The Small intestine

The small intestine is a tubular
structure that carries the food in
continuation with the stomach.
Gall Bladder

The gall bladder stores bile until the
body needs it.
Pancreas

The pancreas creates hormones and
enzymes.
Appendix

Scientist think that the appendix was
used to digest bones.
Enzymes

Enzymes are globular proteins. They
have something called an active site.
The site is a “lock” into which a
substrate “key” fits.
Bile Duct

A large duct that transports bile from
the liver to the duodenum.
Mucus

Mucus is a slimy substance, typically
not miscible with water, secreted by
mucous membranes.
Chemical digestion

Chemical digestion is the chemical
breakdown of food into simpler
compounds.
Mechanical digestion

Mechanical digestion is the first step
in digesting the food you eat.
Salivary amylase

Salivary amylase is saccharidase that
is found in small quantities of human
blood.
Absorption

Absorption, the process by which
matter or radiant energy is taken up
internally, or assimilated ,by a
substance.
Villi

Villi is a microscopic finger-like
projections that line the inner wall of
the small intestine.
Gastric juices

Gastric juices are the colorless, watery,
acidic digestive fluid that is secreted
by various glands in the mucous
membrane of the stomach and
consists chiefly of hydrochloric acid,
pepsin, rennin, and mucin.
Duodenum

The duodenum precedes the jejunum
and ileum and is the shortest part of
the small intestine.
Chyme

Chyme also known as chymus, it is
the liquid substance found in the
stomach before passing through the
pyloric valve.
