How long can your oxygen last in your blood stream after you stop breathing?

Oxygen travels across your lips, into your lungs, across the alveolar-capillary barrier into your blood stream, and then to your cells. This process happens as quickly as it takes you to take a breath and then for your blood to circulate through to the destination cell (a couple seconds to a minute depending on the destination cell and your current rate of metabolism).
Once the O2 Molecule enters your cell, it is utilized as a "final electron receptor" in the last stage of the breakdown of Carbohydrates, Proteins, and Fats. This final stage is termed the Electron Transport Chain, where O2 is split in half and then combined with 2 electrons and two carbon atoms to form H20 (water).
Basically, the oxygen that we breath is not exhaled at all. The oxygen is combined with carbon atoms from the food we eat to form water. The water produced is termed "metabolic water". Some desert animals actually never have to drink because they can survive on just the metabolic water they produce. Neat huh! Humans will keep that water inside of us for cellular use, pee it out, exhale it in our breath, or perspire it through our sweat glands.

∙ 8y agoIt is a simple rule of threes.
You can go without oxygen for three minutes.
You can go without water for three days.
You can go without food for three weeks.
Once you pass that three minute mark without oxygen, you start to damage and lose brain cells which causes irreversible harm to your body.
It is advisable not to go without nutrients the body needs for any prolonged period of time.

What part of the body carries oxygen?
The air carries oxygen to your body when it is inhaled into your lungs.The blood carries oxygen through you body to the vcells that use it as part of their metabolism.
How does pressure affect breathing?
The part it plays in breathing is that when you inhale your rib muscles and diaphragm contract. This means that when you inhale your air pressure lowers and when you exhale your air pressure will risen. This happens because when you inhale your diaphragm will flatten and so will your rib muscles which means its contracting. When you exhale your diaphragm blows up like a balloon and your muscles are relaxing. That is why when you die you take your last breath, by exhaling, because your muscles have to relax because they are not able to work. That is the role air pressure plays in breathing.
Why do you breathe out more carbon dioxide than you breathe in?
There's a process called gas exchange which takes place in the lungs: put simply, both oxygen & carbon dioxide are transported around the body in the blood stream; when the blood reaches the lungs it does a trade - swapping waste CO2 (a by-product of the cellular respiration which is constantly going on in every cell in your body) for oxygen in the air you've just breathed in. So the air you breathe out contains that waste gas, plus the proportion of CO2 that was already in your last breath in.
Explain the difference between breathing and respiration?
Breathing brings in oxygen, which is usually necessary for cellular respiration, in your lungs. Holt Science Book Respiration is the release of energy from food, usually sugar. It is a chemical reaction which takes place inside all living cells. Breathing is the process by which air is drawn into and out of the lungs. When air is in the lungs, oxygen is taken into the body. The oxygen is then used during respiration to 'burn' the food, releasing its energy. When food burns, it produces waste carbon dioxide. This CO2 is passed out of the body from the lungs when we breathe out. So, respiration and breathing are connected, but they are not the same thing. Unfortunately, some people do still use the two words to mean the same thing. Also, the breathing system is also called the respiratory system. Just to make it worse, giving someone a kiss is called artificial respiration, instead of artificial breathing! Breathing is sometimes divided into two stages: ventilation (the movement of air in and out of the lungs) and gas exchange (the absorption of oxygen from the lungs and the release of CO2 into the lungs). One last complication: breathing is sometimes called 'external' respiration, and respiration is sometimes called 'internal' or 'cellular' respiration, there is also aerobic and unaerobic respiration...

How does the oxygen and the carbon dioxide exchange takes place?
Oxygen exchanges occur in the lungs where the circulatory system takes in oxygen and releases carbon dioxide into the lungs. Oxygen exchanges also occur in the capillaries where the circulatory system delivers oxygen to the cells and picks up carbon dioxide from the cells.
Is argon lethal?
It is not toxic but because it takes up space it can displace oxygen and we can't last long breathing an atmosphere without oxygen.
How long would you have to breathe straight helium for it to kill you?
About 2 minutes, the same as you would last not breathing oxygen.
Why can a person last 1 minute without oxygen?
A person can last 4 minutes without oxygen, longer in extreme cold. It takes that long for the body to use up the oxygen in the blood.
Why is oxygen important to your human body?
Oxygen is important cells as without oxygen the human body is unable to release enough energy to support life. In theory any other element in the oxygen-group on the Periodic Table can be used to release energy but because other elements in that group are not easily turned into gases they can't used. Last comment; Oxygen is not important for blood; its important for the blood cells themselves and other cells. Blood and blood cells are very different.
How long would 13 shots last in the blood?
The length of time 13 shots would last in a person's blood stream will depend on their tolerance. This could be anywhere from between 8 and 12 hours on average.
What is the last valve oxygen depleted blood must pass through before pumping to the lungs?
A
Which blood vessel bring oxygen poor blood to the heart from the rest of the body?
With one exception, veins carry oxygen-poor blood back to the heart. The largest and last blood vessel they pass through is called the superior vena cava. The exception is the Pulmonary Vein, which carries oxygen-rich blood from the lungs to the heart to be pumped to the rest of the body.

How does red blood cells affect animal life?
red blood cells carry oxygen around the body and provide us with the oxygen then say the red blood cell is O the circumference is blood and the empty area in the middle is oxygen they last for i think about 3 months then die then go to the liver and get neutralised and the liver makes another. so red blood cells are critical for life

What blood vessels carry oxygen poor blood toward the heart?
With one exception, veins carry oxygen-poor blood back to the heart. The largest and last blood vessel they pass through is called the superior vena cava. The exception is the Pulmonary Vein, which carries oxygen-rich blood from the lungs to the heart to be pumped to the rest of the body.
