About..
THE DIGESTIVE SYSTEM
Provided with a simple explanation on each slide.
To simply ask, what IS the Digestive System?
The Digestive System
The digestive system includes the mouth,
pharynx (throat), esophagus, stomach, small
intestine, large intestine, rectum, and anus. It
also includes the salivary glands, liver, gallbladder,
and pancreas, which make digestive juices and
enzymes that help the body digest food and
liquids.
The Mouth
Salivary enzymes begin carbohydrate
digestion and breaks up the food particles.
The Salivary Glands
Salivary glands play an important role in
digestion because they make saliva. Saliva
helps moisten food so we can swallow it
more easily. It also has an enzyme called
amylase that makes it easier for the stomach
to break down starches in food. Saliva also
has an important role in our oral health.
The Pharynx
Delivers food and liquid to the digestive
system. Pushes food into the esophagus so
it's not breathed in.
The Esophagus
The primary function of the esophagus is to
transport food entering the mouth through
the throat and into the stomach.
The Stomach
Secretes gastric juice and hydrochloric acid.
And activates enzymes, continues to break
down food and kill off any pathogens. Stores
and churns food. Enzyme pepsin digests
protein.
The Liver
The largest organ inside the body. Makes bile
(fluid that helps break down fats and gets rid
of wastes in the body; changes food into
energy, and clears alcohol, some medicines
and poisons from the blood. Stores vitamins
and iron. Destroys old blood cells.
The Gallbladder
Stores the bile made in the liver, then
empties it into the small intestine to help
digest fats. Although in some cases, small
stones may form within.
The Pancreas
A gland that makes enzymes for digestion,
and bicarbonate to neutralize the stomach
acid. And makes the hormone insulin, which
helps turn the food into energy and regulates
blood sugar levels.
The Small Intestine
Digests protein, fats and carbohydrates.
Bacterial metabolism plus nutrient and
excess water absorption. Surface is covered
in villi in greater absorption.
The Large Intestine
Also called the Colon, it absorbs water and
electrolytes from stool. It also contains
beneficial bacteria which helps produce
certain vitamins. This organ also forms and
stores feces. (Tae)
The Appendix
A small, fingerlike pouch that sticks out from
the cecum (the first part of the large
intestine near the end of the small intestine).
Enlarge. The appendix is a small, fingerlike
pouch that is attached to the end of the
colon (large intestine).
The Rectum
The lower end of the large intestine, leading
to the anus. Stores and expels feces.
The Anus
The opening end of the digestive track where
bowel movements leave the body.
