And it pumps that blood to the lungs where the blood gets oxygenated.

Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient carried by the blood.

The alveoli use pressure to move oxygen and nutrients into the blood.

(Non hemoglobin synthetic blood substitutes, known as fluorocarbons, have proved to be less effective oxygen carriers.)

This can also lead to insufficient ventilation and, eventually, low blood oxygen levels.

And then that oxygenated blood is pumped to the rest of the body.

That is blue over here in this diagram, because that blood does not have carried oxygen

You have muscles contract to bring oxygen, a gas, into your lungs, which is then transferred by your bloodstream to every cell in your body.

And then it comes back from the lungs, depicted as red blood, now that it has oxygen in it.

It is recommended not to use steroids or alcohol as these reduce oxygen in the blood which is needed in the joint.

Our studies have found that there is a 42 percent probability of one's blood oxygen going up by one percent if one stays indoors in this building for 10 hours.

When the cells of a body aren't getting the oxygen they need, the nutrients available to the body decrease and toxins build up in the blood.

By decreasing the surface area of the airways, you're increasing the pressure of oxygen moving from the alveoli to the blood.

More breath means more oxygen, and ultimately a greater amount of nutrients that's available for our cells and blood.

Low oxygen levels and, eventually, high carbon dioxide levels in the blood can occur from poor gas exchange due to decreased ventilation from airway obstruction, hyperinflation and a reduced desire to breathe.

In recent years, oxygen has become available for recreational use in oxygen bars.

Our studies have found that there is a 42 percent probability of one's blood oxygen going up by one percent if one stays indoors in this building for 10 hours.

The first limitation is the oxygen oxygen toxicity.

And now the oxygen began to accumulate.

Deoxygenation of the blood increases its ability to carry carbon dioxide this property is the Haldane effect.

And that restricts the blood flow, so all of a sudden you do not have any blood flow going that way, and all of the muscle tissue that needs the blood flow from this point, that needs oxygen from that, it might die in a mild myocardial infarction, or even a heart attack.

In the early twentieth century, researchers began to examine hemoglobin the protein responsible for carrying oxygen from the respiratory organs to the rest of the body in red blood cells.

Any aerobic activity that basically pushes the blood into your brain faster, pushes the oxygen and nutrients into your brain faster helps things repair, pushes the waste out of your brain.

Immediately following the event, blood flow and therefore oxygen transport is reduced locally, leading to hypoxia of the cells near the location of the original insult.

Oxygen saturation is a relative measure of the amount of oxygen that is dissolved or carried in a given medium.

Liquid oxygen

The first limitation is the oxygen oxygen toxicity.

She tripped over her oxygen tank.

Where I left off in the last video, we talked about how the hemoglobin in red blood cells is what sops up all of the oxygen so that it increases the diffusion gradient or it increases the incentive, we could say, for the oxygen to go across the membrane.

Liquid oxygen is obtained from the oxygen found naturally in air by fractional distillation in a cryogenic air separation plant.

So when we have oxygen in the atmosphere we're starting to have an environment where Eucaryotes could at least exist and based on the fossil records on what we looked the DNA has changed over time, I'll do more videos on that, we think that the first Eucaryotes showed up about 2,2 billion years ago, althought there is some debate here, there is some evidence that it might have been a little earlier, a little later,

I'm going to do this in a lot more detail when I make the videos about the heart and our circulation system the blood vessels that don't have oxygen de oxygenated blood is a little bit darker.

Oxygen is reduced.

And oxygen gained hydrogens.

High oxygen content.

A chemical oxygen generator is a device that releases oxygen via a chemical reaction.

Plus one oxygen atom, so I could say one half of molecular oxygen.

And in general, when oxygen is bonding with other non oxygen atoms or non oxygen elements, it tends to have a two minus or a negative two oxidation state.

You may not be aware that I have royal blood in my veins.

Blood poisoning, I shouldn't doubt.

Blood in my veins.

In water, the oxygen acts negative and the hydrogens act positive.

Oxygen has 8 protons.

Oxygen is losing electrons.

Same thing with the oxygen.
