It would actually go and block the artery further downstream and be embolism.

Blood flows through blood vessels.

Subdural hematoma.

Blood runs in the veins.

Blood poured from the cut vein.

Are you ill? The exhaust pipe's broken.

It's gonna be going initially through a giant vessel.

And the capsules in her blood stream.

Shut your mouth!

You know, where did these things come from?

So let's zoom in on one of them....Maybe we can zoom in right over here, that part of the artery.

But there was something left.

The heart is taking a quick breather to refill.

We can do this because tumor blood vessels are unlike normal, healthy vessels we see in other places of the body they're abnormal, they're very poorly constructed, and because of that, they're highly vulnerable to treatments that target them.

And the Arotic valve is going to be what divides the left ventricle from this giant vessel that we talked about earlier.

like red blood cells.

(Laughter)

So, those cells are going to need blood vessels supplying them as well. So, that's what the coronary blood vessels are.

There were blood vessels left.

A needle needs to go right in, so look for the most upright vein.

Some of you may remember that.

So we thought the patient might actually want to know the context as well.

The true capillaries are these guys out here.

And this outer layer, this is the vasculature, which is incredible, around a human brain.

Thrombosis is the process of a thrombus forming.

End to end, that would form a line that would circle the earth twice.

In this example here, it's an artery.

I'll write it out again because I want to make sure we see clearly the difference between someone with compliant blood vessels and someone with non compliant vessels.

So, all these guys over here, these are the true capillaries.

You must inject this directly into her bloodstream.

All the sudden you could have these clotting factors form a clot right over here right at the actual plaque.

Then you start to take a look at adult life.

Can't seem to find a vein.

Oh,clip that bleeder,Mr. Palmer.

Retract the duct a little more laterally.

A blood vessel burst inside his brain.

The vessels are now a little bit less full of blood because a lot of that blood has already left and gone on to the foot and the face and the different parts of the body.

So I went back to the biology of angiogenesis, and started thinking

And this is an X ray showing you the patent, functional blood vessel.

In other words, we can't create supermodel mice.

The walls are covered with villi where nutrient absorption takes place.

The first author, Alexis Carrel, a Nobel Prize winner.

And you can see the vascular tree that remains intact.

I woke up to discover that I had a brain disorder of my own.

And the bottom curve is the weight of a normal mouse.
