What happens if we don't have oxygen to breathe?

Answer 1

If all the oxygen suddenly disappeared, animal life on earth would die suddenly.

If there had never been oxygen anywhere on the Earth, there would be no life as we know it.

If there were no oxygen where you are, you could lose consciousness or even die. .

Oxygen is a crucial requirement of the human body. However if for some reason the oxygen is depleted around the body, then a person will begin to breathe more heavily as the body tries to compensate. The heartbeat will normally increase to carry any available oxygen more quickly. Then various body systems, including the higher functions of the brain, will stop in an attempt to use what little there is for critical brain processes.

Answer 2

Oxygen plays a very important role in breathing and in the metabolism of human beings and all living beings.

We cannot breathe if we do not have oxygen. If we don't have oxygen to breathe, within the first five minutes brain cells begin to die. Brain cells need oxygen to function properly and are very sensitive to lack of oxygen supply. Other vital organ stop functioning and this will lead to suffocation and death.

Answer 3

Without oxygen, our bodies cannot produce energy efficiently, leading to cell death and ultimately organ failure. This deprivation of oxygen can quickly result in irreversible brain damage and death within minutes. Oxygen is essential for sustaining life as it is needed for the process of aerobic respiration that provides energy for all of our bodily functions.
