That's the tip of a ballpoint pen.

And like a tumor, fat grows when blood vessels grow.

We have paper forms to track people who come into clinics.

The Red Cross supplied the hospital with blood.

All these different organs and tissues are gonna be getting blood from the left ventricle.

In this example here, it's an artery.

The brain needs a continuous supply of blood.

Nature feeds the heart cells in your body with a very, very dense blood supply.

And our heart actually has two circuits. But I wanna point out these circuits one at a time. We've already kind of completed one circuit.

It goes to the various tissues and organs and then it comes back on the other side.

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

Royal blood.

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

We're always moving our muscles.

Therefore, when a tumor comes into skeletal muscle tissue, it can't get a blood supply, and can't grow.

Acid for blood.

Something in the blood.

What blood?

Something wrong? It's so fucking bright in here.

And so when people talk about arteries getting blocked or getting clogged, they're talking about the coronary arteries.

Blood flows through blood vessels.

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

And the third challenge is vascularity, the actual supply of blood to allow those organs or tissues to survive once we regenerate them.

Oh, and blood.

You were running the tests on yourself.

Where's that blood?

Blood type, b negative.

So when this guy is jogging, because he has restricted blood supply because the heart is experiencing ischemia downstream from this stenosis, that's why there's heart failure so not able to deliver

It pumps the blood and in particular it takes in the blood from the rest of the body.

And has concentrated acid for blood.

Same rare blood type.

In her blood.

Bring the type specific.

But cancers don't start out like this, and in fact, cancers don't start out with a blood supply.

We don't know what we're talking about.

From your blood.
