How does our body work?

Trying to explain how the body works using simple language would be extremely difficult, if not impossible. In fact, explaining how the body works using the most detailed scientific terms might be impossible because the human body is extremely complex. Many areas of the human body remain a mystery even in what some call the age of modern medicine.

But research and medical experience have taught us enough so that we can get a basic understanding of how the body works. It’s essentially a matter of chemicals and the reactions between various chemicals. Our bodies are made up of numerous chemicals in various combinations. The major ingredient in the human body is water.

Various unique combinations make up the organs of the body, the skin, the bones etc. These organs work together in certain systems to keep the body alive and healthy. We have the blood-circulation system – heart, blood vessels etc. Then there is the nervous system – brain, the hundreds of nerves, nerve cells; the skeletal system – bones, cartilage, tendons; digestive system – mouth, throat, stomach.

Of course, the many different combinations of chemicals come together to form many other organs – liver, kidneys, pancreas etc. Some of these work to help the body eliminate waste and toxins that enter through the air we breath, and the food and water we take in. All of the organs and systems work together to create a larger system that can exist in the climate and atmosphere of the Earth.

The key to all of this is the energy that it takes to keep the body working. We have a particular type of electrical energy that makes the systems work. But there has to be fuel for this “engine” to work. Our fuel is oxygen, water and food. If these are taken into the body in the right amounts our system can use them to remain healthy and even repair damaged tissue, in rare situations.

A human brain is like a central manager of the human body. It processes all the information involved in movement, eating, breathing etc. and gives directions to the various body parts. The other major organ is the heart. This is the central pump for the body. The oxygen that our lungs take in is distributed throughout the body by the blood – a liquid that is pumped by the heart. The food that we eat is broken down during digestion so that the nutrients can be moved through the body as well.

When you have a smoothly running system you put quality fuel in, burn it or process it efficiently then eliminate the waste. This happens with a car – gasoline burned in an engine and exhaust that eliminates the unneeded part of the fuel. The human body does the same thing with food and oxygen, eliminating the unneeded things we don’t need.

There is one crucial part of this process that we haven’t looked at – rest. We must allow our bodies to get sufficient rest so that it won’t be overworked, wear out and break down. If all of these parts are in place the human body can work, as it should.
