oxigen is the gas that enters the blood through the lungs
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 in the lungs and passes through the alveoli, small sacs which allow gas exchange, and enters the blood to be pumped throughout the body.
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.
trachea
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.
Blood enters the lungs through the pulmonary arteries.
It enters through the capillaries of the lungs.
Passages through which air enters the lungs is called the bronchi which branch off of the trachea.
