Inhalation.
Oxygen is the gas that enters the blood during inspiration. It is taken into the lungs from the outside air and then diffuses into the blood vessels in 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.
Oxygen enters the blood in the alveoli of the lungs
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
The air that enters the lungs is richer in oxygen when it enters the lungs. when it leaves it has more carbon dioxide and less oxygen as the lungs expel carbon dioxde and some unused oxygen.

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.
