Tell a story from the perspective of an oxygen molecule traveling thorugh the body.

Explanation:

Me oxygen enters into the human body as a component of air through human nostrils. I enter into the windpipe which get divided into branchial tubes. These bronchial tubes are distributed in the lungs. The brochioles are tiny air sacs which further distributed to the alveoli. I move to alveoli and then further to the capillaries. Through capillaries i move to other body parts along with the blood.
