Ollie the Oxygen Molecule s amazing adventure
t was a warm, summer day. Ollie is floating around a park when he felt a strange sucking feeling. It forces him back into a nasal hole. He turns around and sees spikes lining the walls. As he is forced deeper down in the nasal passage it gets warmer. Ollie reaches out and grabs a spike to stop his journey. The spike is coated in sticky mucus. He realizes this and is so grossed out he lets it go.
As Ollie is pulled down the pharynx it suddenly ends and he sees the epiglottis, a monstrous flap that seals his fate, trapping him in the larynx. He is so focused on the epiglottis he almost misses the vocal cords, inside the famed voice box, they resonate when air passes over them.
The blood cells turn a lighter red as they get oxygen. Once Ollie is in the plasma he is stuck on a red blood cell. Ollie stays in the capillary until the blood cell forces him into another, bigger tube called a vein. The veins keep getting bigger and connecting with each other until it forms the big pulmonary vein, meaning the vein that goes from the lungs to the heart. Ollie flows into the left atrium and is pumped out of left ventricle in the aorta, a big artery. He travels for a long time, switching to several arteries, taking him to the big toe, the tubes steadily gets smaller until Ollie goes into another capillary. He travels down the capillary and notices other oxygen molecules are going from high to low concentration, meaning they are leaving their blood cell and going into a cell and feels himself going into the cell too. He diffuses into a nearby cell.
Ollie moves into the mitochondria and is smashed with Sam, the sugar molecule. A chemical reaction takes place. From this reaction comes Alex, Alexander, Alexia, Alexandra, Alexandria, Abigail, Alec, Amanda, Augustus, August, Arnold, Amy, Angela, Anna, Anne, Anthony, Antony, Andrew, Aidan, Aristotle, Andrea, Adrina, Arthur, Abraham, Abe, Adam, Antonio, Angela, Allen, Andre, Albert, Andy, Abram, Alfred, Alberto, Alberta, Abel, and Abby, the 38 ATPs, Walter the water molecule, and Kelvin the carbon dioxide molecule. Sam and Ollie no longer exist. Ollie has been transformed into Kelvin.
Kelvin the carbon dioxide molecule diffuses out of the cell and into a red blood cell. After a little while he flows into a vein which will take him to the heart. The veins get bigger and combine with other veins until Kelvin was in the inferior vena cava, a big vein that carries blood from the lower half of the body into the right atrium. He then flows into the right atrium and is pumped out of right ventricle, which pumps him into a gigantic artery called pulmonary artery. Kelvin traveling really fast because of high blood pressure.
The pulmonary artery takes him to the lungs and branches off to smaller veins. They keep getting smaller and branching off until they join capillaries. Kelvin is carried into a capillary and sees the alveoli, tiny, grape-like sacs. Because of the high concentration of carbon dioxide, Kelvin diffuses into an alveolus.
Once he is in the alveoli the person he is in exhales and he is forced out of the alveoli and through the bronchioles and bronchi. He flies up the trachea and larynx and tries to grab the epiglottis, but fails and continues moving through the pharynx. He is carried, helplessly, out the throat and into the air.
