Oxygen enters via the lungs.
Oxygen enters your body through the lungs during the process of breathing. The air you inhale contains oxygen, which is then absorbed into the bloodstream in the lungs and transported to cells throughout the body.
The lungs are the organs where oxygen enters the body and carbon dioxide leaves it through the process of respiration. Oxygen is taken in when breathing and carbon dioxide is released when exhaling.
Oxygen enters the blood from the lungs through the process of gas exchange where it diffuses into the bloodstream from the alveoli. In the lungs, carbon dioxide exits the bloodstream and is expelled from the body through exhalation.
Oxygen enters the body through the mouth or nose, passes through the trachea (windpipe), then enters the bronchial tubes in the lungs. Within the lungs, the oxygen is absorbed by tiny air sacs called alveoli and then enters the bloodstream to be transported to cells throughout the body.

The brain uses about 20% of the oxygen that enters the body. Oxygen is crucial for energy production and maintaining brain function. Any disruption in oxygen supply can have serious consequences for brain health.

Oxygen (O2) enters your body through breathing air, which contains oxygen in it. This oxygen goes into your lungs where it is put into the bloodstream, supplied to cells in your body, returned to the lungs as carbon dioxide (CO2), and exhaled through the lungs.
Air enters the body when you inhale (Breathe in) air enters through the mouth and into the lungs. and then exhale (Breathe out) carbon dioxide (CO2)
Oxygen in the lungs and passes through the alveoli, small sacs which allow gas exchange, and enters the blood to be pumped throughout the body.
