So an ischemic stroke is actually very, very similar to what we saw in a heart attack, except it's not occurring in a coronary blood vessel, it's occurring in a blood vessel in the brain.

This is actually an engineered blood vessel.

It mainly affects the aorta (the main blood vessel leaving the heart) and its branches, as well as the pulmonary arteries.

Sometimes it can even completely obstruct the blood vessel.

So we actually perfuse first the blood vessel tree with the patient's own blood vessel cells, and we then infiltrate the parenchyma with the liver cells.

We went to the very heart of the vessel..

So thrombi are these blood clots that form, that can help to obstruct a blood vessel.

Let's say that this is a blood vessel in the brain.

A blood vessel exploded in the left half of my brain.

A blood vessel is made up of two different cell types.

You place the vascular blood vessel lining cells on the inside.

However, as the diameter of the blood vessel decreases further, the red blood cells have to squeeze through the vessel and often can only pass in single file.

Your heart gets more blood flow.

My father'd burst a blood vessel if he heard you say that.

Now If blood is going towards the heart, after the blood is pumped by the heart, it's gonna have to go out to the heart.

I'm actually trying to draw the same blood vessel where it actually breaks.

As this happens, it starts to really really really obstruct the blood vessel.

And what we do is we, to make a blood vessel, same strategy.

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

Now, once the blood vessel is narrowed, that restricts the blood supply so you aren't able to get as much blood through it, so the blood supply is restricted.

Heart and blood vessel diseases still kill more people not only in this country, but also worldwide than everything else combined, and yet it's completely preventable for almost everybody.

So the oxygen can go into this blood and so once the oxygen so this is the vessel that's coming from the heart and then it's just a tube.

Heart and blood vessel diseases still kill more people not only in this country, but also worldwide than everything else combined, and yet it's completely preventable for almost everybody.

let's assume that he is working with my blood vessel and my blood pressure is about 115 systolic over 75 diastolic.

large organ, vascular, a lot of blood vessel supply, a lot of cells present.

Elevated blood pressure can progress to heart failure.

So arteries are blood vessels from the heart.

The coronary arteries supply the heart with blood

We were monitoring his PO2 of his blood, his heart rate, his blood pressure.

And we then can re perfuse the liver with cells, preserving the blood vessel tree.

So what we've next done is we've moved on to looking at blood vessel dilatation.

This actual clot that forms, that can restrict the blood vessel, this is a thrombus.

He is the blood of my heart. Come, Cyfartha.

CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood into the arterial system.

Since the heart is a 'demand pump', that pumps out whatever blood comes back into it from the venous system, it is effectively the amount of blood returning to the heart that determines how much blood the heart pumps out ( Q ).

And in fact, every cell in our body has a little blood vessel that's near by.

You see, last spring I had a slight a tiny convulsion of a tiny blood vessel.

Whenever someone talks about an embolus, or emboli, or embolism, they're talking about something moving through the blood that eventually blocks a blood vessel.

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 the heart relaxes, blood is drawn back toward the heart through open ended pores (ostia).

This right here is blood traveling away from the heart.

So this is the blood going away from the heart.

as the blood pumping from the heart of the whale.

A hemorrhagic stroke to hemorrhage means to bleed, it's literally just a fancy word for bleeding and so in a hemorrhagic stroke you have a situation where a blood vessel can actually break, where you have a blood vessel

We'll talk more in the future of why a blood vessel might break strongly related to high blood pressure and other risk factors, but I don't want to get into that right now but you could imagine if a blood vessel breaks, you have all this blood spewing into the brain in, kind of, an uncontrolled way.
