And for more than 200 years we have

Blood flows through blood vessels.

Blood runs in the veins.

When I made love with my wife, I had no sperm that came out of me

She is bleeding!

Enough blood has been spilt on his account.

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

You have spilled your own blood rather than that of an innocent.

It's a lonely thing, a violin.

No bloodshed in all the city.

Blood has been spilled this night.

They had this motto

When an area of the brain is active, meaning a neural area is active, it gets blood flow shunted to that area.

And that's gonna be dumping into the top of the heart. And then separately you have veins from the legs.

What about the Communists again?

Imagine the blood flowing through your body

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

The blood ran red.

Scientists, sort of at the end of the 20th century,

So again this is right when the heart is squeezing blood out. So we know blood is flowing through here.

That's usually the flow of blood.

This is blood for blood, and by the gallons.

I don't want any bloodshed.

Only fresh zombies bleed, son.

And I bleed... and dance... and plead...

Or must this end with the spilling of your blood?

So you can imagine if you have these things build up, it's narrowing the actual vessel that's supplying blood downstream from that obstruction.

So, everything the part of the plaque that hasn't moved can experience clotting, and the part of the plaque that is dumped in the bloodstream can also clot.

Blood poured from the cut vein.

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

But when you change those behaviors, your brain gets more blood, you think more clearly, you have more energy, your heart gets more blood in ways I've shown you.

The other cool feature about elastic energy is that not only does it lower your pressure which we have talked about, but it also can be used to convert it into movement energy.

Blood ran from his wound.

So there's this actual extra little step here, where blood is going to and from the lungs, and that's the pulmonary flow.

I can hear your blood flowing.

Not everything has to be bang... I'm set. Scream, blood, more blood.

No blood, no foul.

The next blood that spills is gonna be theirs.

The next blood that spills, is theirs.

My head is bloody, but unbowed.

Son, now, I'm sure you don't wanna go spilling blood for no good reason in front of all these decent people now.

These minor changes in blockages caused a 300 percent improvement in blood flow, and using cardiac positron emission tomography, or PET, scans, blue and black is no blood flow, orange and white is maximal.

The police wanted to avoid bloodshed.

Blood ran from his wound.

The same thing happens on this side.
