How does oxygen help humans?

oxygen helps in breathing of the million cells in your body.Blood transfers oxygen to the cells & the cells can carry out their processes with help of oxygen.Since everything requires energy to carry on its processes,human require oxygen to carry out its process of living

Because their bodies are actually craving oxygen so since ice has oxygen, it relieves the body's craving for the oxygen, temporarily. Need to see a doctor.

Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale. \n\nThe diaphragm's job is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. As the diaphragm contracts and relaxes, breathing takes place. When the diaphragm contracts, oxygen is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs. \n\nThese links should help.

It is an enzyme that can counteract the damagging effects of oxygen in tissues. Like the vitamin E.

If a person is on medication for asthma and on oxygen, How can detoxifying help . and will it interfere with the medication which is necessary for them.

haha the answer above me is funny...what what exactly do you want to know about it? theres a lot to do with respiration...theres inspiration where the air is taken in..this is caused by a contraction of the diaphragm..thens there structures like the epiglotis, trachea, pharynx...then the oxygen goes to your lungs..where gas exchange occurs in the alveoli's...this is done by some complicated process that i dont understand really..i didnt really pay attention during this part of physiology/biology class. haha. anyway, the oxygen is picked up by the pulmonary artery and goes to the rest of the body through the aorta...uhh, i can think of anything else..hope this helps!

It comes into contact with oxygen.

Oxygen bind to hemoglobin which is part of the red blood cells.  It is picked up in the lungs where there are little sacs that have a very thin lining of cells.  Therefore the air you breathe in will be able to reach the blood.  Then the hemoglobin will carry blood to the parts of the body.

Those 'oxygen enriched water' machines a scam. They are a way to take money off stupid people.\n\nNo, the human body can not absorb the oxygen present in water. Well, that's not quite true. You could absorb the oxygen in water if you breathed it in. Then you would drown. But if you are just drinking the water or bathing in it you can never absorb the oxygen in it.

A\nOxygen from the blood is used as it circulates through the body. It picks up more oxygen as it passes through the lungs. The heart just pumps it so that it reaches all parts of the body.

Good info Klaus, but you mostly are discussing decompression, in which dissolved gases (usually nitrogen) bubbles out of the blood when going from high to low pressure-Not the reason oxygen is toxic.  The blood requires a certain pressure of oxygen, in other words, and certain number of molecules.  The normal concentration of oxygen in the atmosphere is about 21%, which of course is about perfect.  If you are in an environment that has twice the pressure, you require oxygen at half the concentration, or about 10%.  Its still the same number of molecules total, just a lower concentration.  Clearly, if you are in an environment of 10X the pressure compared to sealevel, you only need a concentration of oxygen of about 2%...again, its still the same number of molecules of oxygen, but because of the greater pressure, there is a lot more total gas molecules present.  Oxygen is a highly reactive molecule, and causes (obviously) oxidation...such as rust on iron.  In the body, this is a toxic effect-More to the point, though, is that the body requires a certain amount of carbon dioxide to maintain the proper acid-base balance.  If far too much oxygen is given, it swamps the ability of hemoglobin to bind CO2, thus causing acidosis-the acidification of the blood.  So, the deeper you dive, the lower *percentage8 of oxygen you require (though again, its the same *amount* of oxygen)- the oxygen is replaced by the most inert gas that can be obtained-helium usually.

Just like how they say on an airplane: "apply the oxygen mask first to yourself and then to your child"... I believe we should make sure we are strong and healthy before trying to strengthen the rest of the world.  There is a strong point that strengthening the rest of the world will help us, too, but if we begin falling apart we won't be able to help ANYONE.

Is this a test question you have to answer?  Increased oxygen provides the "fuel" for your body to function effectively.  Exercise and increased respiration increase blood circulation, providing more nutrients to reach the cells and more waste to be filtered out.  From these basic processes, many other benefits follow.  I'd have to think harder to give you more details - what are you trying to acheive?

Plants dont take away oxygen, they make it.\nPlants taking in what animals and humans breath out and proscesses it through their systems and make it oxygen.\nTry the link-

first: air is warmed by the rich vascular net in the nasal mucosa. Second, air is humidified by nasal secretions. Third, air is filtrated and some gross particles are captured by the endoturbinates, to prevent tehir entrance into the larynx.\n\nThe accesory muscles expand (internal intercostal)or contract (external interconstal)the thoracic box like a pump. that´s the way they help .\n\nCarbon monoxide is very dangerous because it has several times more affinity with the hem group of hemoglobyn than oxygen. So, in an environment rich in carbon monoxide, when inspirated it binds to hemoglopbyn, displacing oxygen molecules from the Hem group and  preventing them to reach the organs, causing tissue anoxia and sometimes death. Treatment involves oxygen therapy, and sometimes a hyperbaric chamber( a place with high concentrations of oxygen in the air, and at a higher atmospheric pressure).

hemoglobin carries oxygen and crosses the placenta from mother to child.  they don't actually breathe until they are born, until that time their oxygen comes from their mothers.

To wake up.  The Body takes in a lot of oxygen because the body is full of carbon dioxide...and carbon dioxide makes you sleepy. So with new oxygen the body feels less tired in a sense refreshed. (Apollo 13)
