Journey of an oxygen Atom

Exhalation

When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity.The air that was rich in carbon dioxide is forced out of the body.

The lungs are now ready for another breathing cycle...

The "Creative" Way

Welcome to Breathe Air Airways. Boarding will start as soon you run out of breath. Its finally time to board. The fellow passengers "Air" rush in. "This is your captain Diaphragm speaking. I will soon tighten my muscles...and air, you are ready to fly. Hope we have a safe trip.

The airways starts descending down the runway, the trachea. Its gaining flight, and its off.

"We have successfully reached the alveolie. Seat belt signs are now off. We will soon be landing. Look outside the window. Your final destination awaits you." (see red capillaries waiting with their baggage.)

As soon as they land, the passengers land, the polite red blood cells rush is to greet the guest for their arrival, the Cappilaries. They exchange of thoughts in the oxygenated and carbon dioxidegenated languages. No one understands each other. But litte to these new oxygen atoms know that they know that they are the real murders of these missing little oxygen atoms?

They are taken to their secret hide - out place, the lungs. Here they meet evil doctor's assistant, know as The Lung. He puts the innocent oxygen atoms in the very cheap but popular, EnergySuckers. They suck the life out of these oxygen atoms and send it to the evilest scientist in the whole body, The Hart.

The life of the oxygen atoms were pumped by Hart and oxgyen - life full blood is spread across the whole body.

Then Hart's team, the trachea, bronchial tubes, diaphragm, get ready for their next target. They have successfully powered the whole body.

Now that I think about it, the oxygens are the evil people, not the carbon dioxide (for this story). The carbons power their whole universe and the oxygens are to selfish to give themselves away. Who do you think are the evil ones?

Journey of an oxygen Atom

What does an oxygen atom look like?

How the lungs work?

What happens next?

Meanwhile, the oxygen rich blood is carried through the network of capillaries and into the pulmonary vein. This vein delivers the blood to the left - side of the heart. This left - side delivers this blood to the whole body.

What happens before?

When you inhale, the air flows right to through these tubes and into the alveoli. This air is full of oxygen. Here, a gas exchange occurs between the air (filled with oxygen) and the red blood cells located in the blood in the capillaries. During the exchange, oxygen from the air passes into the red blood cells in the capillaries. Now this blood becomes very rich in oxygen. At the same time, the carbon dioxide, the waste product, is moved into the the alveoli. The air which now is very rich in carbon dioxide flows through the trachea and alveolie and out your nose / mouth. This is known as exhalation.

Why do we breathe?

When you breathe in through your nose, it filters, wets and warms the air before it passes through the trachea and the bronchial tubes. At the same time, pumps blood rich in carbon dioxide and very low in oxygen to the lungs and through the arteries. The artery end in a mesh of tiny blood vessels which are also know as capillaries. These capillaries surround the air sacs in the end of the bronchial tubes called alveoli.

Parts of the Respiratory System

The "Logical" way...

Your lungs are the most important organs of your respiratory system. They allow you to breathe in from the air. They also allow you to remove the waste carbon dioxide from your body.

The entire respiratory system works together just to breathe the air in and out. Parts of this system are the nose, mouth, trachea (windpipe), lungs, diaphragm , and the bronchial tubes within the lungs.

Air enters the lungs when we breathe in because the lungs expand. The lungs expands because the diaphragm contracts and moves down to make the chest cavity larger.

Our bodies can store many nutrients but it cannot store up one thing we need all the time:oxygen. Every cell in your body has a special job. Oxygen gives those cells energy. Since you can't store that oxygen, your body keeps taking in oxygen in the process of "breathing".
