Not all but most. there is no system, manmade or natural, that is 100% efficent.
the blood absorb oxygen in the lungs(cappilaries)
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 oxygen atoms in water (H₂O) come from the air we breathe. When we inhale, our lungs absorb oxygen from the air. This oxygen is then used in the process of cellular respiration to produce energy for our body's cells.
Yes, when we breathe in, oxygen from the air enters our lungs. This oxygen is then absorbed into the bloodstream through tiny air sacs in the lungs called alveoli.
Oxygen enters the lungs when we inhale air. It travels down the airways and reaches the alveoli, tiny air sacs in the lungs where gas exchange occurs. Oxygen from the air diffuses into the bloodstream through the alveolar walls and is then carried to the rest of the body.

they absorb oxygen directly from the air without lungs.
Alligators are air breathers. They inhale and exhale through their nostrils. Their lungs absorb oxygen from the air that they inhale.

the answer to that is RESPIRATION
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.
you give your lungs less time to absorb the oxygen in the air because you breath it out immediately.
Amphibians use their lungs for respiration, but they also absorb oxygen through their skin. They breath underwater by absorbing dissolved oxygen in the air or gills.
Raccoons breath in oxygen just like any other mammal. They inhale oxygenated air through the mouth and nose into the lungs. The lungs absorb the oxygen and excrete carbon dioxide.
