The process of biological air traveling in the body (breathing movement) a 200-word fairy tale

Hi! Hello everyone! My name is oxygen, which is a colorless and odorless gas. Although it looks unremarkable, there is a saying that "all that glitters is not gold". I am one of the raw materials for photosynthesis and an indispensable substance for cell metabolism.

I went to the human body a few days ago, which was very exciting! Of course, I have also made many contributions to the human body.

Before entering the human body, I have to go through two quarantine, one is the filtration of nasal hair in the nasal cavity, and the other is the adhesion of trachea. After these two inspections, I can successfully reach the waiting hall-alveoli. My main means of transportation is a yacht-red blood cells. I don't know how long I stayed on the yacht, but I finally landed on a continent called histiocyte. The residents here are hardworking and United, and there is an oxygen processing plant. The treated oxygen turns into carbon dioxide. Because of my love for new things, I will not hesitate to devote myself to processing and manufacturing.

After processing, I look brand new, and then I can't wait to leave my body and live a completely different life! May everyone sincerely bless me!
