The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
The lungs absorb oxygen from the air.
Green algae absorbs oxygen from the surrounding water. Land plants had to evolve to absorb oxygen from the air.
The lungs are the organ that gets oxygen into the blood.
The blood carries the carbon dioxide from the body cells to the lungs so the lungs can release the carbon dioxide when you exhale
The respiratory system and the circulatory system. The respiratory system has the lungs bringing in air to your body. Then that oxygen you get is transported around your body via the circulatory system.

The lungs remove oxygen from the air.
Oxygen is latent in the water, because the water absorbs gasses in the air, like how water absorbs sugar. Since the air (and so oxygen) is in the water, the oyster can use it.
Pyrogallol,when in alkaline solution, it absorbs oxygen from the air, turning brown from a colourless solution. or simply none
Your body absorbs some of the oxygen out of air in your lungs

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.
