Is cutting off the oxygen supply to the brain...?

You cant suffocate yourself by holding your breath or putting you hand over your mouth/nose. Your body has a built in survival instinct. However , if you use something over your head you just might suffocate. That is why they put warnings on things such as plastic bags that say they are not a toy.\n\nMessing with breathing is dangerous. At the least if you have no oxygen for several minutes you will suffer brain damage.

Cutting the aorta will kill you in seconds, but it's very hard to get to (thank goodness!)\n\nOh and by the way, check these out:

No, certainly not.\nEuthanasia is playing God.\nFor God alone gives life and He alone has the right to take it.\n\nBesides, plenty of comatose patients have woken up. Also, strange on-the-brink-of-death miracles prove that modern medicine isn't fully equipped with brain-death related issues.\n\nIf in extreme pain, use pain-killers (alternate medicine, etc).

cutting off blood supply to the organ and it starts deterirating
1064539
yes, yes and NO.  Due to low concentration of oxygen in our lung blood, oxygen passes thru thin cell walls into blood.  Due to higher concentration of Carbon Dioxide in our blood, it passes into the air in our lungs and is expelled.  Each exhale has less oxygen and more carbon dioxide than the inhale breath.\n\nHowever, there is still plenty of oxygen left, not all passes into our blood.  That is why mouth to mouth resuscitation works.  Plenty of oxygen in our exhaled breath to help with someone Else's inhaled breath.

YES!  \nAbsolutely it does!\nYou are not taking in the proper amount of oxygen therefore not oxygenating your blood stream/muscles/lungs properly.

interesting question. I'm not sure I think it would depend on how you die. If it was something that would affect your brain like spine injury or stroke probly not but maybe if you have a heart attack your brain can still process for a few seconds while it still has blood that your heart stopped and you are dying. I do know that the brain can still work when cut off from the body (for a few seconds.) When they decapitated people they told them to blink until they couldn't anymore and the people would blink for almost 30 seconds after the head was cut off until they bleed to death. Kinda scary...

because the body cannot live without BRAIN

Isn't that kinda like asking what would happen if humans didn't depend on oxygen anymore?\n\nIt ain't gonna happen, so don't worry about it.

They're both critical but basically the oblongata is involved with breathing and heartbeating due to its connection with the spinal cord so it is very crucial. On the other hand, Cerebrum damage is like a common term "brain damage" so it might just alter your function at the least.

That 10% story has fallen to Urban Myth status.  New medical imaging techniques can now show which parts of the brain are in use during particular functions, such as speaking, reading, listening to music, etc.  Turns out that your brain uses many differnt parts to do most functions, but certiain functions TEND to concentrate in particular areas.\n\nWhat remains of the myth, though, may actually help understand what I said in the last paragraph.  Many people who have hade severe brain damage and loss of many functions, can sometimes regain at least some ot those functions when the brain learns to use other, undamaged parts to do what the damaged parts used to.\n\nYeah, a vital organ.  An artificial heart can keep a person going, but with no brain, even a beating heart runs in an empty shell.

I have seen people brought back to life that previously did not have a pulse or breathing. So I don't think the previous answers are accurate. \n\n To answer your quesiton sometimes I have seen the exact opposite I think they go too far trying to save people.  I have seen people in comas. I have also taken care of people who had strokes(that were revived) that would have preferred to die.

Its like gas for a car. Blood is a oxygen carrier, and supports all the body organs. If anyone loses too much of it- too bad!

YES.Since the brain is essentially a storage facility for ones experiences through the five senses and able to triage information (much like an emergency room nurse determines which cases are most urgent and which ones can wait), a transplant without the memories coming along for the ride would make very little sense. Emotions are an integral part of our memory too.  I can't\n imagine that being lost in the transfer.  What do you think the fate of the brain removed will be?  The donor will be the recipient as well.  Dig it.

Yes.. If you dont want to stop breathing and die, energy is eused.

Depends on how severely you severed it.  If it was totally cut at the C7/T1 (there is no C8 in most mammals) you would probably cut off ennervation and autonomic control of the heart and lungs, which would, in general, be very bad.

Yup, oxygen oxidises our bodies. As we are carbon based lifeform, we lose carbon when we breathe out - hence, carbon dioxide.
