Previous answer: between six and 10 percent... 4 percent if you are a politician ;). Popular misconceptions don't come any more popular and misconceptiony than this one. Indeed, its origins lie so far back that nobody knows who said it first (various 19th Century quacks believed it, based on skull m…easurements and whatnot). The concept has since been plugged by everyone from advertisers to psychics, but - boring as it sounds - actual science has shown that we do indeed use just about all of our brains throughout the course of every single day. The mechanisms of the brain may not be fully understood, but the idea of a vast bulk of grey matter lying dormant and mysterious is a myth. Thank you Mr. Fry! 15% of total resting cardiac output is supplied to the brain. This represents 50-55ml blood flow per 100 grams brain tissue per minute, or 750ml total blood flow per minute.

You don't use all of it but you do use a lot of it i am not 100% certain how much you use though
Oxygen gets into the bloodstream by diffusing across the layer of cells on the surface of the lungs and into the body fluid and then becomes attached to hemoglobin. The rate at which this happens depends on the concentration of oxygen in the lungs. As the diffusion process takes place across the …surface of the lungs, there is less and less oxygen remaining in the air sac of the lung and so the process slows as time goes on. To keep the rate of oxygenation at a high level, it is better to replenish the partially depleted air with fresh air by breathing. ( Full Answer )
Yes, because oxygen is a gas and water is a liquid. So their properties don't mix.
We breathe in air which is actually a mix of many different gases. Oxygen is the portion of the air that is absorbed through our lungs into our blood stream.
we all living beings use all of (nearly all of) our brain, i.e. approx. 100% of our brain.
Yes you do. See we breathe in oxygen and we breathe out carbon dioxide. Plants are the opposite. They breathe in carbon dioxide and breathe out oxygen. We give them carbon dioxide and they give us oxygen!! That's how we breathe!!!!!!!
Oxygen doesn't help us breathe, it's why we breathe; oxygen is needed by every cell in the body as part of cellular respiration, which is how the body produces its internal energy; we breathe to take oxygen into the body, & without it we would be dead.
You use 20% when you are awake.Recent tests of the brain show thatyou use up to 50% of it whilst you are sleeping. This is also thetime when your body is healing most. For that is Why we sleep
It is a common myth that we (mammals including humans, and other animals) use only a small percentage of our brains. We have so much information to process, store, recall, as well as basic bodily functions to manage that our brain is always in constant motion.

100% of the brain. If we only used 10% we would have the thinking power of a sheep. Anyone who quotes the "ten percent" figure is probably correct ... regarding themselves.
The brain uses oxygen in the same way other organs do. Within every cell in the brain, tiny organelles called mitochondria take up oxygen and use it to convert glucose into a usable form of cellular energy - adenosine triphosphate (ATP). Without ATP, neurons would very quickly lose their ability to …fire and the whole brain would eventually shut down. ( Full Answer )
We get oxygen from the trees. They produce the oxygen that we need to breath and live.
If you are providing 2 liters per minute of oxygen to a patient what percentage of oxygen are they breathing?
Human lungs are 2 liters in volume by average. So... Average breath rate is 12 breaths per minute. In one minute the patient would take in 24 liters of air. You are supplying 2 liters of pure oxygen + 4.8 liters from air (20% of the 24 liters (Percent oxygen in dry air)) = 6.8 liters of Oxygen per m…inute. 6.8 liters oxygen / 24 liters intake = 28.3% Oxygen or you can look at the table given by the books at http://www.fpnotebook.com/ER/Procedure/LwFlwOxygn.htm Nasal Cannula, Flow 0 liters per minute: 21% (Room Air), Flow 2 liters per minute: 29% But I like the mathematical method. That's just me! ( Full Answer )
You have to breathe in something! Oxygen + Carbon Dioxide = Glucose and water Glucose is a form of sugar and gives the body energy.
At sea level, the atmosphere contains about 21% oxygen. At higher altitudes this level decreases.
we breath in oxygen and breathe out carbon dioxide.. we breath in oxygen and breathe out carbon dioxide.
Although the brain constitutes only 2 percent of our body mass, it uses 20 percent of the oxygen.In other words, the brain uses up a fifth of the oxygen we breathe.This leaves the brain highly prone to damage during anoxic reactions or episodes.After approximately four minutes without blood(containi…ng oxygen, I'm sure you know), brain cells begin dying. ( Full Answer )
when you inhale air into your lungs the concentration of oxygen in the blood can be no greater than that in the air.As the blood reaching the lungs is lower in oxygen there is transfer from the air to the blood stream until the concentrations stabilise.However there is no active transfer.Therefore t…here will always be Oxygen in exhaled air even if the initial oxygen concentration in the blood is zero as the air oxygen and the blood oxygen will reach a steady state equilibrium ( Full Answer )
Yes. Elevated oxygen levels for too long can make you lose your vision. That's why premature babies are often blind when they grow up. Take Stevie Wonder for example.
The sun gives Vitamin D, nothing else. It gives energy to plants, which then give oxygen.
All of it. The "10 percent" figure you occasionally see is nonsense that a lot of people believe just because they've seen it so much. The number of neurons firing at any given time is usually low, but that's like saying you only use ten percent of your muscles because you're not running and jumping… and waving your arms and bending over and straightening up all at the very same time. ( Full Answer )
its not researched till now people say that the last person was enstine to use more of his brain
concentrate on what you want and increase your ability of that certain area of the brain.
Some studies say 8-10% is the amount of the brain that the average person uses. It is unclear about how they tested and/or proved this, but that is what is most commonly known.
We use all of our brain. You don't have your entire brain active at any one time though. For example, you have nerve cells to detect all of the possible colours, but you are not always seeing all of the colours. Similar with sound, pain, taste, smell.... You are not moving all of your muscles at o…ne time either. So there are many cells in the brain that are not currently being used because the situation does not require their use. A grand-mal seizure is when brain signals go out of control and you have too much activity in the brain. Using all of your brain at once would not make your smarter, it would be chaos.

According to sources Einstein's brain was removed within seven hours of his death and within next 24 hours this was declared that he used 14% oh his brain and he is first on earth to do so. This has since been found to be a complete fallacy.
We don't really know much about how thought actually works, but we do know that whoever came up with the "ten percent" figure was actually using considerably less than that at the time ... it's completely, entirely wrong in nearly every possible way.
The oxygen that you breathe is involved in aerobic cellular respiration. It is the last electron acceptor in the electron transport chain, and then combines with hydrogen to form water. Without oxygen, electron transport cannot continue because the electrons and hydrogen would get backed up. If this… happens, the organism, including humans, will die. ( Full Answer )
Fish use their gills to breath in oxygen. You know...the skin flappy things on the side of their faces? Yeah. Those.
Yes, you breath in oxygen that plants give off and breath out carbon dioxide that plants take in.
The notion that we only use some fraction of our brain is based on an oversimplification of an outdated understanding of how the brain actually works (in other words, it's wrong). It may be true that at any given time only a small fraction of your neurons are firing, but that's more because you don'…t often have a need for the neurons that govern, say, remembering exactly what benzaldehyde smells like (cherries, if you're interested). There's no reason to think that geniuses use a "higher percentage" of their brains than anyone else.... they just do it better, somehow, and we really don't understand exactly how. There is no secret, chemical or morphological, behind a genius using his brain more effectively and successfully than many others. He simply keeps his neurons free of other electrical and chemical impulses, impurities, disturbances, disruptions, cross-currents and short-circuits such as those caused by sudden or continuing erruptions of anger, hate, lust and so on. The ancient Indian philosophers have defined this state of the resultant chemical and electrical special balance as Cleanliness Of Conscience or Kundtalini. Where many people are prone to diverge in their thoughts, emotions and feelings, they are clear-conscious enough to make them converge, thereby reducing the need for using more neurons. Anyway complex thoughts result in the formation of more chemical combinations and more intense and intricate electrical discharges. The projecting of the fore head frontwards in the cource of evolution increased the internal volume of the skull by which more quantity of brain could it contain, which has been critical in the emergence of intellect in man. The erection of the backbone unlike in animals also has been a critical factor. When the backbone remained horizontal to the axis of the Earth, all the excess energy produced was being arrested and pulled down to earth by the gravitational force. But once it became erect, it was freed from the magnetic pull of the earth and all excess and unused energy went straight to the brain and it developed. It is not strange that a sitting sleeper is more conscious and alert than a lying sleeper. When compared to animals, all men are geniuses once they get rid of all rubbish in their brain and do not overcrowd it. ( Full Answer )
Oxygen is in the air, and when you breathe in the oxygen gets into your lungs and is absorbed into the red blood cells.
There is no difference in nationality. It is said that "people use 100% of their brains" and not just the rumored 10-30%.
No. Normal air is about 20% oxygen, 79% nitrogen, and 1% "other gasses". That's what you inhale when you breathe. Your exhalations - what you breathe OUT - is about 79% nitrogen, 16% oxygen, 2% carbon dioxide, 2% water vapor, and that 1% of "other" gasses. When you perform artificial respiration, …you are breathing OUT, directly INTO the victim's mouth. Your exhalation of 16% oxygen is plenty for him to survive on. ( Full Answer )
The early Earth atmosphere was toxic until the Stromatolites converted it to the nitrogen/oxygen mixture we now have. It is maintained by the trees and algae.
Contrary to common belief, the entire brain is used. The myth that we only use 10% of our brain started because doctors didn't know what some of the parts did. on the other hand some seem to use only 10 percent if you look at how the world is going . All of the human brain is being used all of the …time, just because you arent always running doesnt mean your muscles arent always being used; same with your brain. Nobody knows how much of the brain is used. There is probably some redundancy in the system as there is in every other system in our body. This lets us recover from strokes and head injuries, and continue to think as we age (as neurons die off). The factoid (something that sounds true but isn't) is that we only us e 10% of our brain. The 10 percent statistic may have first been stated by William James (1842-1910) when he said "we are making use of only a small part of our possible mental and physical resources" (The Energies of Men, 1908). However no specific "brain use rating" can be determined and in any event he said resources or capacity, not brain hardware. The wording shifted with repetition to be "brain" not "resources" and we wound up with the present incarnation of this statement. Even on the basis of evolution we would probably have pared down the amount of useless brain sometime in the distant past as the brain consumes 20 percent of body oxygen and places significant energy and maintenance demands on the body. Just like our muscles not all the brain is in use at once. The parts of the brain are not equally active active (and luck for us too, as the brain activity creates heat and we don't have the cooling capacity to support that!). It is possible that, like muscles, you can strengthen the brain and get more use of it. But also, like muscles, no one can expect to get 10 times stronger or smarter by exersize. That is known as the "10 percent myth" , actually, Brain imaging research techniques such as PET scans (positron emission tomography) and fMRI (functional magnetic resonance imaging) clearly show that the vast majority of the brain does not lie fallow. Indeed, although certain minor functions may use only a small part of the brain at one time, any sufficiently complex set of activities or thought patterns will indeed use many parts of the brain. The normal human uses all parts of the brain at one time or another, but the percent of brain use at any given time is dependent on the circumstances. For example, during important life-endangering situations more of the brain is likely to be used. Watching paint dry, however, requires a fraction of the brain activity. The idea that we only use about 10% of our brain is a common myth. A relevant excerpt from a recent article states: "First of all, it is obvious that the brain, like all our other organs, has been shaped by natural selection. Brain tissue is metabolically expensive both to grow and to run, and it strains credulity to think that evolution would have permitted squandering of resources on a scale necessary to build and maintain such a massively underutilized organ. Moreover, doubts are fuelled by ample evidence from clinical neurology. Losing far less than 90 percent of the brain to accident or disease has catastrophic consequences." The very last sentence answers the question for us. Even a tiny fraction of brain loss results in problems, which suggests all of the brain area is important and vital. In addition the various parts of our brain have been mapped as being related to specific functions (some to do with memory, some with deeper thinking etc.) The whole brain is used for a wide variety of purposes, both conscious and subconscious, voluntary and autonomic.

If you breath 100% Oxygen, it is not immediately poisonous and can be beneficial for a short time. However the human body has evolved to breath a gas mixture called air. Air is 80% Nitrogen and 20% Oxygen and if you breath a gas mixture significantly richer in Oxygen for a protracted period, then th…e Oxygen affects the functioning of most body systems and can lead to death. Also breathing Oxygen where the partial pressure of the Oxygen exceeds 1.2 bar, can cause acute oxygen poising resulting in convolutions. SCUBA divers need to take this into account when diving, especially on mixed gasses. ( Full Answer )
I don't know but look it up instead of giving that a test. seoriously, just look it up.
Even before they had names for the gases in air they played games with candles. Exhaust breath will allow a candle to burn, but not as long as fresh air.
Yes, it is widely used in hospitals for medical purposes, and for welding through oxyacetylene. In 1923 the American scientist Robert H. Goddard became the first person to develop a rocket engine ; the engine used gasoline for fuel and liquid oxygen as the oxidizer. Goddard successfully flew a s…mall liquid-fueled rocket 56 m at 97 km/h on March 16, 1926 in Auburn, Massachusetts, USA. Low pressure pure O 2 is used in space suits. Smelting of iron ore into steel consumes 55% of commercially produced oxygen. In this process, O 2 is injected through a high-pressure lance into molten iron, which removes sulfur impurities and excess carbon as the respective oxides, SO 2 and CO 2 . The reactions are exothermic, so the temperature increases to 1,700 Â°C. ( Full Answer )
A respirometer. This is a device used to measurethe rate of respiration of a living organism by measuring its rateof exchange of oxygen and carbon dioxide.
If there is a problem with us breathing oxygen, we all have a very big problem. The Earth's atmosphere is composed of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. It is common practice in trauma treatment to supplement additional oxygen to the… patient. Finally, it is a common practice in casinos to pump in more oxygen. Perhaps you want to look at your data and rethink your question. ( Full Answer )
100%. All of the oxygen that I breathe comes from the air! The answer that you were probably after, but did not ask, was about the percentage of oxygen in the air that we breathe. The questions may sound similar but they are not the same. The answer is a little over 20%.
the air goes into your lungs. In your lungs there are billions of tiny air sacs. Surrounding each air sac is a network of blood capillaries. The air sacs and the blood capillaries are separated by a thin membrane. Across this membrane the air sacs give the blood capillaries oxygen and they blood cap…illaries give the air sacs carbon dioxide. We breathe out this carbon dioxide! ( Full Answer )
The percentage of oxygen in the atmosphere is 20.75%. The atmosphere has many other elements that we breathe in besides oxygen. Oxygen needs to be present for life on earth.
Every living organism on the planet, from the smallest of bacteria to the largest mammals need oxygen to survive.
Isaac Newton use his brain to its maximum level he use his brain to110 %
Our metabolisms take advantage of a reaction between oxygen gas andcompounds such as glucose to release energy. Oxygen compounds donot contain the same energy and do not react in quite the same waywith other substances, so we cannot use them. Most substances thatare as reactive as oxygen are toxic, …but we have adaptedspecifically to be able to use oxygen. ( Full Answer )
About 20 % probably. This is very high as compared to the weight of brain.
