  • Answer: mitochondria use oxegen and glucose to make water, carbon dioxide and produce energy in aerobic respiration which is required to live.
  • Answer: The vital function that oxygen serves in the human body isrespiration. Oxygen is needed for the lungs to function and for theproper functioning of other vital organs such as the heart andbrain.
  • Answer: It may help to step back and think about what blood does, and why it would matter that the blood is rich in oxygen (or CO2).Among other things, blood acts to transport oxygen and CO2 to or from tissues and organs, right? In order for the blood cells to carry them, the binding site on the blood cell would have to be open.So, if the blood is oxygen rich, that means that those blood cells are carrying as much oxygen as they can...there is simply no room for any CO2 to bind to the cells.So the reason it never mixes is because the oxygen is hogging the blood cells binding sites (or vice versa).
  • Answer: yes, oxygen in its elemental form is naturally corrosive and so might be harmful.although, the amount does not matter as much as the purity does. pure O2 would not let you live for too long.the oxygen used in hospitals is suitably mixed with other gases so that it does not harm the human body systems and at the same time provide pure healthy air
  • Answer: Oxygen is very important to the body. It is important in the breaking down of glucose for energy to the cells
  • Answer: Oxygen is very much important for the human body. Oxygen plays a vital role in the breathing processes and in the metabolism of the living organisms.
  • Answer: About 6 minutes before brain cells start to die. If a person has a cardiac arrest resuscitation has to begin within this time to be successful. The time may be prolonged if the body is cooled, for example by drowning in ice cold water.

    As mentioned, temperature (specifically metabolism) plays a very big role in how long you can go without oxygen, but as general guideline:
    • Heart: Needs constant oxygen
    • Brain: 4-6 min
    • Kidneys: +- 30 min
    • Muscles: +- 2-4 hours
    • GI Tract: +- 12 hours

    Thus, the main areas of concern is the heart and the brain.
    A human body ca only live for six minutes without oxygen, before the brain cells start to die.
  • Answer: I think the role of oxegen is to deliver energy to your body.
  • Answer: Oxygen plays a massive role in the human body. Oxygen isresponsible for delivering nutrients to the cells in the humanbody.
  • Answer: Oxygen, hydrogen and carbon and a little nitro-gen and boom life, if there is the
    spark of love and warmth I am not the expert, oxygen is an oxidizer if there are
    too many oxygen atoms, if oxygen is alone it only wants a friend to cling to.
    Burning is the common thought of oxygen, such as providing warmth from food
    as fuel for heat. Heat is the main reason for eating oxygen and carbon and hydrogen.
    Sugar is the main plant food similar to C12 H22 O11, so the role of oxygen is to get
    oxygen (O12), into the burning cells and combine oxygen so heat takes place. Then waste
    is important, and bunching up atoms and molecules with proteins to line new cell
    walls as they oxidize or split apart like a tiny atom bomb, (the a-bomb is extremely
    toxic), but heat is released by the agitation. Without oxygen they say you die, you
    actually mummify instantly because oxygen is everywhere and it is impossible to have
    oxygen vanish, if you have the miracle mineral magnesium in your body you make
    oxygen deep in your cells because magnesium burns under water by releasing more
    oxygen and feeding on that oxygen. So eat it.
  • Answer: There a number of important elements that the body uses: C,H,N,O,P, S (CHNOPS). As you see nitrogen is one of these 6. The most important use is in the nitrogen bases. These include DNA and RNA. Each has a nitrogenous base. The ones in DNA code for proteins. This code is for production of an organism such as ourselves. RNA also has bases and RNA is important in the "reading" and "translation" of these bases.
