The job of your heart is to pump blood through your body. Even in your 

sleep, your heart keeps pumping. If it stopped, you would quickly die. 

Your heart is divided into two sides. Each side of your heart is broken 

into two sections known as the atrium and the ventricle. Each side of the 

heart has an atrium and a ventricle for a total of four chambers.

Your right atrium pumps blood to your 

lungs through the right ventricle. In 

your lungs, your blood again fills up 

with oxygen and returns to your 

heart. Your blood now enters the left 

atrium of your heart. It is then 

pumped out to your body through 

your left ventricle. You don't even 

feels this Happening do you? Its a 

simple yet complicated process.

Did you know it only takes 10 seconds for blood to travel from 

your heart to your big toe and back again. 

Oxygen is used by your cells as it 

performs the functions of life. As 

your body uses oxygen, your cells 

produce another gas known as 

carbon dioxide. It is important that 

your body has a way to get rid of it.

The main parts of the respiratory 

system is the nasal cavity, pharynx, 

trachea, lungs, Bronchi/Bronchioles 

and Diaphragm.

The job of your respiratory system is very simple: To bring oxygen into 

your body, and remove the carbon dioxide from your body. Your body 

needs oxygen to survive. 

The nervous system is about action and senses. If you see a bike that 

might hit you, you jump out of the way. In that example, your nervous 

system was involved in many ways. Your eyes saw the bike, your brain 

figured out the bike might hit you, and your brain told your muscles to 

make your legs jump out of the way. You sensed and then acted. 

The nervous system also senses 

activity inside of your body. 

Most of the nervous system 

responds inside of your body. 

The response is not in your 

control. Your body 

automatically senses and reacts 

to something in a organ or cell .

You are holding a hamburger in your hand with a bite missing out of it. In 

your mouth you have a small wet ball of mashed up burger, bun, 

ketchup, mustard, and saliva. So what's next? Your food begins the 

process called digestion. It then goes down the Esophagus like a water 

slide and into the stomach which is where your food is broken down and 

stored for energy. Then the rest 

of process occurs in the 

intestines which is broken 

down even more and brings 

out the non nutrient pieces 

and removes water while 

being

pushed through the intestines. 

After the tour through the 

intestines the burger in its new 

physical appearance is then 

excreted from your body. 

The big purpose of the muscles found in your body is movement. We 

could be talking about the movement of your legs while you walk. We 

could be talking about the beating of your heart.

You have no control over most of 

the muscular system. You do 

control the muscles in your 

arms, legs, neck, and torso. You 

have little or no control over the 

heart muscles. 

Did you Know? Your muscular system 

is closely connected to the nervous 

system.
