1. DIGESTIVE SYSTEM

2. DIGESTIVE SYSTEM IS
RESPONSIBLE FOR THE PROCESSING
OF THE FOOD THAT WE EAT. IT
CARRIES OUT THE PROCESS OF
DIGESTION, WHICH IS THE PROCESS
OF BREAKING DOWN OF FOODS INTO
SMALLER PARTICLES, PREPARES THE
FOOD FOR USE BY THE BODY CELLS.

Mouth
Esophagus
Stomach
Small Intestines
Large Intestine
Rectum
Anus

4.  Mouth is the first part
of digestive system
which receives the
food that we eat. Food
is broken down by our
teeth into smaller
particles by means of
chewing.

5.  Next path of the food is the
esophagus; it is a tube that
connects our mouth to the
stomach (also known as
gullet).
 We have the so called
epiglottis, it is placed at the
top of the windpipe that
acts as a gate and closes so
that the food does not go
down the windpipe.

6.  The main function of the
stomach is to store food.
The stomach has flexible
walls which can expand or
contract depending on the
amount of food inside.
Stomach produces
hydrochloric acid that kills
germs inside of it.

7.  Small intestine where most of the digestion process
takes place, it is long, coiled, tube which can extend
for more than 6 meters. It serves as the main
absorber of digested food for delivery into the
various parts of the body. Here, food is digested into
very small particles that it can be finally absorbed by
the blood in the body.
 It is where we can find the so called villi, one that
absorbed the digested food in the small intestine.

8.  Large intestine foods that
are digested go here. It is
about 5cm wide and 1.8m
long. Its function is to
reabsorb the water and
minerals in the undigested
food and bring it back to
the body. Without this, our
body would be
dehydrated.

9.  Rectum is located at
the end of large
intestine. Solid
waste is placed here
or stored, until it is
brought out of the
body through the
anus.

10.  Anus is the opening at the end of
the rectum.
