Download Digestion System

By: Chris Arnold and Kenji Easter
Functions:
Your digestive system is all about getting food into your body,
digesting the food, absorbing the nutrients you need, and
elimination of the materials you don't need.
Once you put the food in your mouth, you start to chew and begin
a process of mechanical digestion that grinds food down into a
pulp.
Your body also starts to release enzymes that start the process of
chemical digestion and the breakdown of biological molecules.
Most chemical digestion happens in the stomach.
The food moves through your digestive system and is eventually
broken down into compounds and nutrients that your small
intestine can absorb into the blood stream. The material you don't
absorb continues into the large intestine where water is removed
from the material and then whatever is left can be eliminated at
your convenience.

Systems it interacts with
The digestive system works really close with the circulatory
system to get the nutrients distributed through your body.
The circulatory system also carries chemical signals from your
endocrine system that controls the speed of digestion. The
digestive system also works together with your excretory
system (kidneys and urination). While the digestive system
collects and removes solids that are not digested, the
excretory system filters compounds from the blood stream
and collects them in urine. They are closely connected in
controlling the amount of water in your body.
How this body system works
You get hungry and you eat. Once you put the food in your mouth, you start
to chew and start a process of mechanical digestion that grinds food down
into a pulp.
Your body also starts to let out enzymes that start the process of chemical
digestion and the breakdown of biological molecules. Most chemical
digestion happens in the stomach. The food moves through your digestive
system and is eventually broken down into compounds and nutrients that
your small intestine can get into your blood stream. The material you don't
absorb goes into the large intestine where water is removed from the
material and then whatever is left can be eliminated at your convenience.
