Oxygen Molecule
This is Mike and Moo the oxygen molecule. Fun fact, We are two atoms that formed together to create a molecule. You are going to join us on our journey through the human body.
Step 1: Entering The Respiratory System
We Have Entered!
We are very important but we work hard
Woohoo! We just got inhaled through the mouth, which can also happen though the nose. You can guess which one you think is better.
Beginning Of Our Journey

Once we got sucked in by the black hole of a mouth. There was a split at the end. We went on the left side because when in doubt go with left.
Then, we realized we were traveling down the bronchus and the ways kept splitting over and over again. Lots of exercise. We then made it into the bronchioles.
Step: 2 We are Survivors!
Continue Down The Road!
After we traveled down the bronchioles, we made it to the void that is the alveolus.
Not many oxygen molecules make it this far but Moo and I are pretty cool, what can I say. But, we did not really know what to expect next.
Made Some Friends!
We ran into a huge bond, a red blood cell. We got carried into capillaries, which is a tiny blood cell. We were diffused into by alveolus venules.
Oh! The Heart.
Me and Mike made it into the heart with our new friends by the left atrium which went to the left ventricle and we were shot BANG! into an artery.
Then! we, the oxygen molecule was confused because heart rate began to speed up, which was explained by our blood cell friends that it needs more oxygen and the human body must be doing something to pump up the heart beat.
We arrived to the Capillary and washed through the arteries and aterials. We made it to the big toe!
The red blood cell let me and Moo off there.
We diffused through the wall of capillary through the cell membrane of a muscle cell! Very exciting experience.
As we were almost done, we ended up getting used in the process of creating an ATP. I was then separated from Moo (shh! do not worry we reconnect in a bit :))
Step 3: To The End!
I got bonded to two hydrogen atoms to create water, we were back in the blood stream and heading back to the heart through that whole process again. We pumped through the heart and then Moo and I arrived back in the alveous, then the lungs and on our way back out!
