What happens to the oxygen in the body of a healthy person?​

What happens in the process of respiration? (Oxygen is brought into the lungs via breathing, where it is transported by red blood cells to the entire body to be used to produce energy. Once the red blood cells return to the lungs, the "burnt" carbon dioxide is exhaled. How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called hemoglobin in the red blood cells then carries the oxygen around your body.

It is brought into the lungs when the healthy person is inhaling, once they exhale some oxygen is let out.
