A flow chart, like this one, shows how a process begins and ends, and the steps in between.
The process can be of almost any kind, from manufacturing a tire to creating an advertisement.
Therefore, learning how to describe and explain a process in English is important.
It's important for teachers, engineers, and people who provide customer support.

One process that we are all familiar with is our body's circulatory system.
This system provides oxygen throughout the body and eliminates carbon dioxide, which is a waste product.
If something goes wrong with this system, we need to repair it quickly, or we die.
So it's important to understand it and keep it functioning properly.
What happens with something goes wrong with the sysetem can't be repaired? -If it can't be repaired, we will die.
It provides oxygen to the body and eliminates carbon dioxide.

A flow chart, like this one, shows how a process begins and ends, and the steps in between.
If something goes wrong with this system, we need to repair it quickly, or we die.
What does the circulatory system do? -It provides oxygen to the body and eliminates carbon dioxide.
It provides oxygen to the body and eliminates carbon dioxide.
It’s important to keep it functioning properly, or we will die.
First, the most important requirement for the system to work is a supply of air.
Without fresh air with sufficient oxygen, the process won't keep us healthy and alive.
So the process begins by breathing in air, which happens when the lungs expand and draw in air.
Once inside the lungs, oxygen in the air is exchanged for carbon dioxide in the blood.
This exchange happens when blood cells release carbon dioxide and absorb oxygen.
This blood is now oxygenated blood, which means it carries oxygen.
What happens inside the lungs? -Oxygen is exchanged for carbon dioxide.
Once inside the lungs, oxygen in the air is exchanged for carbon dioxide in the blood.This exchange happens when blood cells release carbon dioxide and absorb oxygen.
What kind of air is require to keep us healthy and alive? -fresh air with sufficient oxygen
(1) After exchanging CO2 fox oxygen,oxygenated blood flows to the heart.
(2) From the heart it is pumped to the rest of the body.
(3) The carbon dioxide which was exchanged for oxygen is breathed out.
(4) This happens when the lungs contract.
To summarize, the process begins by inhaling air and oxygenating the blood.
The oxygenated blood in the lungs then flows back to the heart.
The CO2 which came from the blood is exhaled, and the next cycle begins.
Where does the CO2 come from? -blood that comes from the heart
How does the process begin? - by inhaling air and oxygenating the blood
Where does the oxygenated blood go? -back to the heart
Note that the blood in the lungs flows in a loop from the heart.
The blood which enters the loop from the heart carries carbon dioxide.
Once the carbon dioxide is exchanged for oxygen, the blood continues through the loop and exits into the heart.
The oxygenated blood is then pumped to the rest of the body.
How does the blood in the lungs flow to from the heart? -It flows in a loop that connects the lung and heart.
Inside the lungs, oxygen in the air is exchanged for carbon dioxide in the blood.
The system won't work without a supply of air.
From the heart it is pumped to the rest of the body.
Once inside the lungs, oxygen in the air is exchanged for carbon dioxide in the blood.
The blood travels to and from the heart in a loop that begins and ends in different parts of the heart.
What happens to the oxygenated blood after flows to the heart? - It pumps to the rest of the body.
To stay healthy and alive, we need fresh air with sufficient oxygen.
The process begins by inhaling air and oxygenating the blood.
This happens when the lungs contract.
This exchange happens when blood cells release carbon dioxide and absorb oxygen.
Without fresh air with sufficient oxygen, the process won't keep us healthy and alive.

The Circulatory System 2
As you can see, everything depends on the flow of blood to and from the heart.
So how does the heart do this?
First, the heart, which is a muscle, has 4 chambers.
From one chamber, blood is pumped to the lungs.
This is the blood that carries carbon dioxide.
When the oxygenated blood from the lungs comes back to the heart, it enters another chamber.
This chamber is called the left atrium.
In addition to a supply of air, the circulatory system ...depends on the flow of blood to and from the heart.
(1) First, the heart, which is a muscle, has 4 chambers.
(2) From one chamber, blood is pumped to the lungs.
(3) This is the blood that carries carbon dioxide.
(4) When the oxygenated blood from the lungs comes back to the heart, it enters another chamber.
What does the blood pump to the lungs carry? -it carries CO2
(1) First, the heart, which is a muscle, has 4 chambers.
(2) From one chamber, blood is pumped to the lungs.
(3) This is the blood that carries carbon dioxide.
(4) When the oxygenated blood from the lungs comes back to the heart, it enters another chamber.
From the left atrium, the oxygenated blood is pumped into another chamber, the left ventricle.
The left ventricle then pumps the blood into the aorta, which is the largest artery in the body.
From the aorta, the oxygenated blood passes through a network of smaller arteries throughout the entire body, including the brain.
Blood returns to the heart through a system of veins and enters the upper right chamber, the right atrium.
What is the largest artery in the body? -the aorta
From the left atrium, the oxygenated blood is pumped into another chamber, the left ventricle.The left ventricle then pumps the blood into the aorta, which is the largest artery in the body.From the aorta, the oxygenated blood passes through a network of smaller arteries throughout the entire body, including the brain.
What does the heart use to pump blood throughout the body？- a network of arteries and veins
From the left atrium, the oxygenated blood is pumped into another chamber, the left ventricle. The left ventricle then pumps the blood into the aorta,which is the largest artery in the body. From the aorta, the oxygenated blood passes through a network of smaller arteries throughout the entire body, including the brain.
Now that we understand a little about the circulatory system, we can ask what it needs to operate.
Of course it can't operate without energy.
This energy is supplied by another system, the digestive system, which gets energy from food.
And of course these systems need to be supported and controlled.
Our skeletal system provides support, and our muscular system provides control and movement.
Without support and movement, we couldn't get the food that we need for energy.
Only plants can do this because they have a completely different system, which gets energy directly from the sun.
What supplys energy to the circulatory system? - the digestive system
What provides physical support for our bodies? -the skeletal system
Without support and movement, we couldn't get the food that we need for energy. Only plants can do this because they have a completely different system, which gets energy directly from the sun.
What life forms get energy directly from the sun? -plants
To summarize, the human body is like a huge, complex factory.
The language we use to describe how it functions is the same language we use to describe almost any industrial process.
The vocabulary is different, but the processes, flows and logical relationships are almost identical.
Think of some familiar process in your life or job and see if you can describe and explain it in English.
What is like a huge, complex factory? - the human body
Our bodies function very much like a huge, complex factory.
From one chamber, blood is pumped to the lungs.
