Aflow 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 tyreto 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’s support. one process that we are all familiar with is our body’scirculatory system. This system provides oxygenated blood 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. First, the most important requirement for the system to work is asupply of air. Without fresh air with sufficient oxygen, the process won’t keep our healthy and alive. So the process begins by breathing in air which happens with long expand and drown in air. Once inside the lungs, oxygen in the air is exchanged for carbon dioxide in the blood. This exchange happens whenblood cells release carbon dioxide and absorb oxygen. This blood is now oxygenated blood which means it carries oxygen. To summarize, the process begins by inhaling air and oxygenatingthe blood. The oxygenated blood in lungs then flow back to the heart. The C O 2 which came from the blood is exhaled and the next circle begins.

Oxygenated blood in the lung flow in the heart. The blood which enters in a loop from the heart, carried carbon dioxide. Once the dioxide exchanged for the oxygen, the blood continues through the loop and exist into the heart. The oxygenated blood is then pumped to the rest of the body.

As you can see, everything depends on the flow of blood to and from the heart. So how that the heart does this. First, the heart, which is a muscle has 4 chambers. From one chamber, blood is pumped to the lung. This is the blood that carry carbon dioxide. When oxygenated blood from the lungs comes back to the heart, it enters to another chamber. This chamber is called the left Atrium(左心房). From the left Atrium, the oxygenated blood is pumped toanother chamber, the left Ventricle(左心室). The left ventricle then pumps the blood into the aorta(主动脉) 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.

Now that we understand a little about the circulatory system, we can add what we need to operate. Of course, it can’t operate without energy. This energy is supplied by another system, digestive system, which gets energy from food. And of course, this system need to be supported and controlled. Our skeletal system provide support and our muscular system provide control and movement. Without support and movement, we couldn’t get the food for energy. Only plants can do this, because they had a completely different system, which gets energy directly from the sun.

To summarize, human’s 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 logically relationships are almost identical. Think of some familiar process in your life for job, and see if you can describe and explain it in English

The process begins by inhaling air and oxygenating the blood.
