11. Conclusion
1.The digestion
process first
occurs in the
mouth. In the
mouth, food
chewed and
crushed by the
tooth, aided by
the tongue. In the
mouth there is
also a digestive
enzyme that
helps the enzyme
amylase.
2.Having digested in
the mouth, the food
will go into the
esophagus. Food is
pushed by the
esophagus into the
stomach muscles.
This muscle
movement called
peristalsis. Peristalsis
that causes food
pushed up into the
stomach
3.In the stomach, food is chemically
digested with the help of an
enzyme called pepsin. Pepsin plays
convert proteins into peptone.
Inside the stomach there is
hydrochloric acid which causes the
stomach becomes acidic.
Hydrochloric acid is produced by
the stomach wall. Hydrochloric acid
serves to kill germ and activates
pepsin. When the digestive process
occurs in the stomach, the stomach
wall muscles to contract. This
causes the food to be mixed and
stirred with enzymes and
hydrochloric acid. Gradually, the
food would be a form of porridge.
4.Then, the food has undergone
digestion will move little by
little into the small intestine.
The small intestine is where
digestion and absorption of
nutrients. In the
duodenum, the digestion of
food occurs with the help of the
sap of the pancreas. Pancreatic
lymph produced by the
pancreas gland. Lymph
containing pancreatic
enzymes, such as the enzyme
amylase, the enzyme
trypsin, and lipase enzymes.
12. 5.After passing through
the small intestine, the
remaining food into the
colon. In the large
intestine, food wastes
decay. Decomposition is
aided by the bacterium
Escherichia coli. Water
and mineral salts from
the rest of the food, will
be absorbed by the gut
again.
6.Finally, the rest of the
food expelled through
the anus in the form of
feces.
Digestive system is designed to process food
and fluids consumed each day. How useful the
digestive system for human life.
