Which one of your organs do not need oxygen?

ALL of the the organs in the human body need an oxygen supply. This even includes the organs responsible for delivering oxygen to the rest of the body: the heart and lungs. Every organ requires oxygen. All that can be said in this case is that some organs use/need more oxygen than others. For instance, the brain needs/uses more oxygen than the spleen.


What human organ uses the most oxygen?

Oxygen is needed for aerobic respiration in the mitochondria in our cells. Therefore, it would be reasonable to assume that the cells which respire most need the most oxygen ie. our muscles. The muscles need far more oxygen relative to other systems in our body, due to the fact that they respire most. This is especially true during rigorous exercise.


Why do human need to breathe in order to stay alive?

Humans need to breathe in order to take in oxygen from the air, which is essential for the body to produce energy through a process called respiration. Oxygen is used to fuel the cells in our body and remove waste products like carbon dioxide. Without oxygen, our cells would not be able to function properly, leading to organ failure and eventually death.
