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 our body through the process of respiration. When we inhale, air containing oxygen enters our lungs. The oxygen then diffuses from the air sacs in the lungs into the bloodstream, where it is carried by red blood cells to tissues throughout the body.
Oxygen enters the blood in the alveoli of the lungs
Oxygen diffuses into the blood from the air in the lungs. This occurs in the alveoli, which are small air sacs in the lungs where gas exchange takes place. Oxygen crosses the thin alveolar membrane and enters the bloodstream to be carried to the body's tissues.
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 blood in the alveoli of the lungs
When air enters the body through the nose or mouth, it travels down the trachea (windpipe) into the lungs. In the lungs, oxygen is exchanged with carbon dioxide through the alveoli, small air sacs where gas exchange takes place. This oxygen is then carried to individual cells in the body through the bloodstream.

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.
