The lungs remove oxygen from the air.
we breathe in oxygen and we release carbon dioxide
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.
There is more oxygen in the air.
Inhaled air is richer in oxygen than exhaled air.
About 21% of air is oxygen.

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.
we breathe in oxygen and we release carbon dioxide
Nitrogen was found by Daniel Rutherford in 1772 by removing oxygen and carbon dioxide from the air.
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.
