We'll start with the blood flow.

Imagine the blood flowing through your body

133Xe has also been used to measure blood flow.

This measures dynamic blood flow and therefore energy flow within the brain.

And you can see that the halo of blood flow disappears after treatment.

You can see his wounds, you can see blood flowing.

So it would be destructing the blood flow downstream right over there.

In the arm, you can measure blood flow in the arm by how much it swells up as some blood flows into it.

If you had all of the hemoglobin sitting in your blood plasma, it would actually hurt the flow of the blood.

So ischemia is deprivation of blood flow and oxygen downstream from this right over there.

There is no change in blood flow, in dilatation of the blood vessels.

You can imagine all these blood flows, as plaque grows, the blood flows become a little turbulent around these plaques.

Their presence implies thrombosis at a site of rapid blood flow that happened before death.

Many types of heart defects exist, most of which either obstruct blood flow in the heart or vessels near it, or cause blood to flow through the heart in an abnormal pattern.

When it happens, you are significantly depleting the blood flow going downstream from there.

Your hepatic artery branches off of this to get blood flow to the liver.

The blood doesn't just flow out someplace and then come back someplace else.

Imagine the blood flowing through your body I was told at UCLA Medical Center as one sealed system.

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.

This is because aortic insufficiency causes increased blood flow in the ascending aorta.

Angiography does not visualize atheroma it only makes the blood flow within blood vessels visible.

They are part of the Circle of Willis, which provides backup circulation to the brain.

In that general process we talk about the restriction of blood flow, that is ischemia that's happening.

A doctor sits beside him, whose quick steady hand may mend a bone, or stem the life blood's flow.

SPECT is a nuclear medicine study that looks at the blood flow and activity, it looks at how your brain works.

So this right here is an embolism, but either way, you're blocking the blood flow further down the brain, which could cause infarction, that brain tissue will die, and whatever that brain tissue did for mental function, or whatever, is going to make it very hard for this person who is experiencing this stroke to do those things.

A doctor sits beside him, whose quick, steady hand may mend a bone, or stem the life blood's flow.

It also gives blood flow to your stomach so it's very important in digestion and all that.

Well that's the forearm tagging on the triceps.

Venous stasis, or venostasis, is a condition of slow blood flow in the veins, usually of the legs.

The brain's blood circulation is capable of disposing of excess heat by increasing local blood flow.

learned that they could track blood flow to map non invasively where activity was going on in the human brain.

Now in the left ventricle, after it's done pumping, it expands and that oxygenated blood flows into the left ventricle.

After the burst of activity the blood flow to the cerebral cortex in the area affected is decreased for two to six hours.

This allows an organ to maintain constant flow despite a change in central blood pressure.

When blood vessels constrict, the flow of blood is restricted or decreased, thus retaining body heat or increasing vascular resistance.

This is a study a high fat meal, and within one or two hours blood flow is measurably less and you've all experienced this at Thanksgiving.

Now this plaque has rupture. It got so big. Maybe the turbulent blood flow helped stimulate this and whatever else.

Too little blood flow (ischemia) results if blood flow to the brain is below 18 to 20 ml per 100 g per minute, and tissue death occurs if flow dips below 8 to 10 ml per 100 g per minute.

And then creating space and the rhythm of space, using the surface of the balls, the surface of the arms.

I want to be clear, embolus is the general term for anything that can float around in your blood and eventually lodge itself at some point in your circulatory system and restrict blood flow.

I think you'll have an idea of how these strokes are different and how they interrupt the blood flow to different parts of the brain.

In principle, this is a negative feedback control system that seeks to balance cerebral blood flow to its demand.

In men of his class, vigor and resolution are entirely a physical matter, and ooze out with the flowing of the blood and the gigantic fellow really looked piteous in his helplessness.

In fact, the so what is, in the brain, changes in neural activity, the things that make your brain work, the things that make your software work in your brain, are tightly correlated with changes in blood flow.
