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.

Tree's metabolize carbon dioxide into oxygen and also absorbes other pollutants. When a tree is cut down all the bad pollutions that it has absorbed to clean the air is then realease back into the air we breath.
The most important organ of our respiratory system is the Lungs. The lungs are the organs that extract or absorb oxygen from the air we breathe and fills our blood with life giving oxygen.
Betta fish breathe air....yes... that's right... they breathe air. They breathe air because they have an organ by their gills that is called the Labyrinth's Organ which allows them to breathe air. They breathe air by coming up to the surface of the water. Then they gather air in their mouths and hold their breath underwater.
