Can human body absorb Oxygen presents in water ?

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.

No, they break up water molecules into oxygen and the rest they use.

Well... as far as biology goes... no.  They don't need air... just oxygen.\n\nIf our bodies were capable of breathing in water to extract oxygen we'd do it... unfortunately, we cannot handle liquid in our lungs, hence the drowning bit.  We do get better gas transfer from water... however our bodies cannot generate the force to expell the liquid under normal breathing conditions.

Put a fish in the water and see if it dies, if it doesnt then there is oxygen in the water. If it does then shame you have to buy another fish!!!

yes.\n\nEverything you injest goes to your fetus.  For that matter, things you absorb through your skin can pass to your fetus, as well as what you breath.

the brain is the largest consumer of oxygen in our body, though it is one of the smallest organs .......brain requires lot of oxygen every minute and the availability of oxygen therefore infleuences the working of brain\n\nwhen we retain our breath, level of oxygen entering our body is minimised.....As a result, the brain doent get sufficient oxygen and the thinking process slows down

Without a lifejacket, the boater will still most likely continue breathing, even if unconscience.  The body is trying to sink, but lungs filled with air will keep the body afloat.  If the person breathes in and his or her lungs fill with water, the person will definitely sink. However, after drowning, the gases in the blood stream accumulate, allowing the dead body to rise to the surface of the water.

isnt it obvious? we cant breath underwater.. unless we have gills like the fishes!!!

They have breathing holes on their heads.When they need oxygen,they will swim onto the surface of the water and take in the oxygen.

Breathing, the process whereby an organism (living thing) obtains oxygen from its surroundings, to take part in internal chemical reactions which break down food to release energy. Breathing also usually gives out waste carbon dioxide as an unwanted by-product of these reactions. Breathing is one aspect of respiration, which is a term that includes both physically obtaining oxygen, and also using it in chemical pathways inside cells to release energy—the process of cellular respiration\n\nMany aquatic animals obtain oxygen dissolved in the water by muscle-powered movements, such as when the forward motion of a fish or the pumping actions of its mouth and throat force a flow of water over its gills ( See also Fish). This is underwater breathing. Tiny organisms “breathe” by the process of passive seepage or diffusion of oxygen through their body surfaces. Plants also obtain oxygen by diffusion from the air or water around them, usually into the leaves.

well in Titanic most of the people died of the cold and had no water in there lungs and they were wearing life jackets. All the other movies (that i can remember)the body had been in the water for a very long or very short time. short= air still in you  Long = decaying gases but once those gases are gone you sink.\nUseless side note: If someone drowned in the  1700's or 1800's  and they couldn't find the body because it had sunk they would shoot a canon over the surface of the water . the vibrations would make the remaining air or gas inside the body collect in pockets and might make the body it float. Worked sometimes.

During pregnancy, there is a stage where the human fetus has gill slits, but by the time a baby is able to survive outside it's mother, these have disappeared.  Babies, as we would think of a baby, can NOT breathe underwater- they have air breathing lungs, just like you, and would drown.\n\nThere is something called the mammalian dive reflex, which slows respiration, and can allow someone to survive for a short time (perhaps a few minutes depending on the circumstances) under water just from the oxygen they receive from the water, however this works best in very cold water, which has more dissolved oxygen.  People with smaller bodies, like babies and young children are more likely to survive longer under water.  This is where stories of kids serviving under lakes for long periods (15 min, or so) come from.

Yes they are. Gasses being dissolved is a physical reaction, not chemical reaction. Therefore, they can dissolve without losing stability or neutrality. Thus, they can easily be dissolved in water, much the same way that they can be dissolved in air.\n\neg: \nHe(g) -> He(aq)\nHelium does not form or break any bonds, it does not reduce or oxidize, it simply does not react. It does, however, give off energy in this physical raction (as does any dissolving substance). \n\nAnother good example would be a stable compound dissolving. For example there is dissolved oxygen gas in water, even though oxygen gas is a stable compound...

Higher partial pressure of O2 in atmosphere that that present in the blood.\n\nRemember, blood in the lungs will be DEOXYGENATED!

3/4 th of the human body is water. Blood is the best medium for water to circulate the water along with blood, so that no part of body gets dehydrated.The blood mostly consists of plasma which is mostly water. Thus most of the blood or almost all the blood is water.

They will do it by passing the water over their gills. Fish gills are full of blood vessels containing carbon dioxide. Through the process of osmosis, the small oxygen atom that makes up the water molecule is absorbed into the bloodstream and exchanged to carbon dioxide.
