The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Mostly arteries.

alveoli
Oxygen passes from the blood into organs through the wall of capillaries.
The lungs. Oxygen enters our lungs as part of the air that we breathe. It goes to the blood vessels deep in our lungs and then on to all parts of our body.
The organ that takes in oxygen is the lungs. While in breathing process, oxygen passes through the lungs from the air by means of inhaling.
The lungs are responsible for exchanging oxygen and carbon dioxide with the blood. Oxygen is taken up from the air into the blood through the alveoli, while carbon dioxide is expelled from the blood into the lungs to be exhaled.
Blood is the only fluid connective tissue in our body. It passes through every single blood capillary, tissue, and organ in our body. Hemoglobin in our red blood cells carry oxygen which is essential to the function of all the organ systems in our body.
blood take oxygen from blood.
The brain consumes 40% of the oxygen in your blood.
