What is the Digestive System

• The digestive system is consisted of large hollow
  muscles that enables their walls to move. That
  movement causes the walls to move food and
  liquids throughout the body and nutrients are
  dissolved into the body during digestion

Mouth

• The mouth secretes saliva that allows the
  swallowing process easier.
• The mouth is where we start the digestive
  process.
• We have different types of teeth that do
  different jobs. We have ones that tear the food
  and ones that chew the food.

Back to Question 2.
5
Esophagus

• After the food is chewed up it is then swallowed.
  The food goes down a tube called the esophagus.
  Here the food is pushed. When the food
  approaches a ring at the end, the muscles relax
  so the food can pass to the next step.

Back to question 3.
6
Stomach...part one

• The stomach has 3 mechanical tasks to do. First
  the stomach has to store the swallowed food and
  liquid. For this to happen the muscles in the
  upper part of the stomach must relax and allow
  large portions of swallowed material into the
  stomach

Back to question 4.
7
Stomach...part two

• The second part of the stomach mixes up the food
  and liquids. During this part there are also
  juices produced by the stomach to make digestion
  easier.

Back to question 7.
8
Stomach...part three

• The third part of the stomach, the lower part,
  prepares the materials that were just mixed, and
  slowly passes everything to the small intestine.

9
Small Intestine, Liver, and Pancreas

• In the small intestine more digestion is
  occurring. Here all materials are dissolved from
  juices produced by the pancreas and the liver.
  These contents are mixed and processed for
  further digestion

Back to question 5.
10
Large Intestine

• The large intestine is used for storing food
  residues and to absorb water
• The large intestine had about 5 gallons of fluid
  pumped through daily which that fluid leads to
  reabsorbation.
• The large intestine leads food material to the
  colon.
• It has 6-8 contractions per day and sweeps
  material all the way to the rectum.

Back to question 6.
11
Colon

• All digested nutrients are absorbed through the
  intestinal wall. What is left, unknown fiber,
  older cells, and any undigested food particles,
  all this is pushed to the colon and waste is
  discarded by bowel movements.
