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.
Water does not contain air, but it can dissolve some gases like oxygen and carbon dioxide. When water is aerated, it absorbs air molecules into its structure, but it does not actually contain air in the same way the atmosphere does.
The cornea in the eye does not receive oxygen from blood. Instead, it gets its oxygen directly from the air.
Your body absorbs some of the oxygen out of air in your lungs
The respiratory system absorbs oxygen. Oxygen is inhaled through the nose and mouth, passes through the trachea, and enters the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
The lungs provide oxygen to cells by extracting oxygen from the air we breathe and delivering it to the blood. The blood then carries the oxygen to all cells in the body.
The lungs absorbs oxygen into the blood
The organ that absorbs oxygen into the blood is the lungs. Specifically, the alveoli, tiny air sacs within the lungs, facilitate the exchange of oxygen and carbon dioxide. Oxygen from inhaled air diffuses across the alveolar walls into the surrounding capillaries, where it enters the bloodstream. This process is essential for delivering oxygen to tissues throughout the body.

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
The lungs are the part of the human body that absorbs oxygen directly from the air. When you breathe, the lungs take in oxygen from the air and transfer it to the bloodstream to be transported to cells throughout the body.

The organ that supplies a human's bloodstream with oxygen from the air is the lungs. When we inhale, air enters the lungs, and oxygen from the air diffuses into the bloodstream through the alveoli, tiny air sacs where gas exchange occurs. This oxygen-rich blood is then circulated throughout the body to supply tissues and organs.
