Oxygen enters the body by being absorbed into the blood (specifically, it is absorbed by red blood cells which contain an oxygen-carrying compound known as hemoglobin) when air is inhaled into the lungs, which have a highly porous, spongy structure which facilitates the exposure of blood to the air.
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)
The blood gets oxygen in the heart. Once the oxygen has been replenished, the blood is sent back out to the organs.

Oxygen plays a massive role in the human body. Oxygen is responsible for delivering nutrients to the cells in the human body.
When oxygen enters the bloodstream through the lungs it generally binds to red blood cells (more specifically the hemoglobin within red blood cells), which are carried along within the plasma. While some unbound oxygen may become diffused inside the plasma itself it is not the primary or intended mean of oxygen transport throughout the body. In short, plasma doesn't carry oxygen, but instead carries the cells that carry oxygen.
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 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 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.
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 (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.
