Esophagus
Stomach
• The internal organ in which the first part
of digestion occurs, being (in humans and
many mammals) a pear-shaped
enlargement of the...
Small intestine
• The part of the intestine that runs
between the stomach and the large
intestine; the duodenum, jejunum, and
ileum collectively.
Large intestine
• The cecum, colon, and rectum collectively.
Liver
• Special uniform worn by a servant or
official.
Appendix
• A tube-shaped sac attached to and
opening into the lower end of the large
intestine in humans and some other
mammals.
Pancreas
• A large gland behind the stomach that
secretes digestive enzymes into the
duodenum. Embedded in the pancreas are
the islets of Langerhan...
Gall bladder
• The small sac-shaped organ beneath the
liver, in which bile is stored after secretion
by the liver and before release into the
intestine.
Enzymes
• A substance produced by a living organism
that acts as a catalyst to bring about a
specific biochemical reaction. Most
enzymes are...
Bile/bile duct
• A bitter greenish-brown alkaline fluid that
aids digestion and is secreted by the liver
and stored in the gallbladder

Mucus
• A slimy substance, typically not miscible
with water, secreted by mucous
membranes and glands for lubrication,
protection, etc.
Chemical digestion
• Digestion is the mechanical and chemical
breaking down of food into smaller
components that can be absorbed into a
blood stream, for...
Absorption
• The process or action by which one thing
absorbs or is absorbed by another: "shock
absorption".
Mechanical digestion
• The breaking of food into digestible
chunks, normally using the teeth.
Salivary amylase
• Amylase is an enzyme that breaks starch
down into sugar. Amylase is present in
human saliva, where it begins the
chemical process of...
Villi
• Any of numerous minute elongated
projections set closely together on a
surface, typically increasing its surface
area for the absorption...
Gastric juices
• A thin, clear, virtually colorless acidic fluid
secreted by the stomach glands and active
in promoting digestion
chyme
• The pulpy acidic fluid
that passes from the
stomach to the small
intestine, consisting
of gastric juices and
partly digested food.
Duodenum
• The first part of the small intestine
immediately beyond the stomach, leading
to the jejunum.
