DIGESTIVE SYSTEM
The digestive system consist of a;; the parts of the body
working together to help turn food and liquid into the
building blocks and fuel the body needs.
ESOPHAGUS
The esophagus is like a stretchy pipe that's about 10
inches (25 centimeters) long. It moves food from the
back of your throat to your stomach. But also at the
back of your throat is your windpipe, which allows air
to come in and out of your body. When you swallow a
small ball of mushed-up food or liquids, a special flap
called the epiglottis flops down over the opening of
your windpipe to make sure the food enters the
esophagus and not the windpipe.
THE RESPIRATORY SYSTEM


The right lung is slightly bigger than the left
The respiratory system is the system of the body
that deals with breathing when we breath the
body takes in the oxygen that it needs and
removes the carbon dioxide that it doesn't need
CIRCULATORY SYSTEM


Red blood cells may live for about four months
circulating throughout the body feeding 60
trillion other blood cells
The blood is the transport system by witch
oxygen and nutrients reach the body's cells and
waste materials are carried away. The heart, a
muscular organ positioned behind the ribcage
and between the lungs is the pump that keeps
this system moving.
NERVOUS SYSTEM
•QUIK FACTS
•The central nervous system contains the brain and spinal cord
•A neuron (nerve cell) is the basic unit of structure and function of the
nervous system
•A response that is made automatically is a reflex
What is the nervous system?
Made up of your brain, your spinal cord, and an enormous network of
nerves that thread throughout your body, it's the control center for your
entire body. Your brain uses information it receives from your nerves to
coordinate all of your actions and reactions. Without it, you couldn't exist!
