Oxygen enters the blood through the process of respiration in the lungs. In the lungs, oxygen diffuses from the alveoli into the blood capillaries surrounding them. It then binds to hemoglobin in red blood cells for transport to tissues throughout the body.
Oxygen enters the blood in the alveoli of the lungs
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 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 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.
Blood low in oxygen enters the right atrium of the heart through the superior and inferior vena cava.
Blood entering the left ventricle is rich in oxygen. In contrast, oxygen-poor blood enters the right ventricle.
Oxygen enters the blood in the alveoli of the lungs
Oxygen enters the pulmonary blood in the capillaries of the alveoli -- the air sacs of the lungs.

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.
When blood that is rich in oxygen re enters the heart, the blood enters through the pulmonary valve. The pulmonary valve brings the oxygen rich blood to the pulmonary trunk of the pulmonary artery.
