Baby's blood.

But for the sake of demonstration ... I think we should turn on the lights.

You're dead.

The streets will run red with blood... women's blood.

DONATE YOUR BLOOD TO THE RED CROSS

Its blood is red. It must have hemoglobin.

was crimson with his blood

It's not like donating to the red cross

And those red molecules are hemoglobin.

And it's in every cell.

It's a few cell layers thick. On the inside you have some red blood cells bumping along.

Blood... so red...

Grim was the relish you took as you licked the warm blood cool!

The yellow green area is the fluid of blood, which is mostly water, but it's also antibodies, sugars, hormones, that kind of thing.

And it doesn't have any mitochondria, no mitochondria.

Yeah, his blood wasn't even red.

I grew up with the colors of war the red colors of fire and blood, the brown tones of earth as it explodes in our faces and the piercing silver of an exploded missile, so bright that nothing can protect your eyes from it.

The Red Cross supplied the hospital with blood.

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

We only suck nice crimson blood of it.

I'm just gonna kind of try to target a couple of the tissues that I think people sometimes might have questions about.

I was very, very sick.

So that has no mitochondria, and it's not really using oxygen.

If we were to shrink you down, smaller than the smallest thing you can see with the naked eye... you will find that your piece of hair starts to look... a lot more interesting.

And we all have them.

They found these red circular looking objects, and they looked, for all the world,

The active ingredient is resveratrol, it's also found in red wine.

And one of them, I woudn't really call it tissue, but you can definitely call it cell type. It's the RBC, and RBC just stands for red blood cell.

So people sometimes wonder, you know, if the red blood cells are carrying oxygen to other parts of the body.

Vampire blood. Jiogulan.

So that's why I switch it in this point blue colored vessel to red colored vessel.

These are literally amazingly designed cells that are made for the purpose of carrying around oxygen to the body, because they literally are bags of hemoglobin.

I mean, you've got red ones, and blue ones, and the blue ones are the veins, and the red ones are the arteries but are they part of the systemic flow, or pulmonary flow, or something else?

Kill!

As he slurped the red blood, he heard frenzied screams.

And to answer this question, I would have to remind you that the red blood cell basically looks a little bit like this, right, in cross section.

This is highly thrombogenic material. Thrombogenic, very fancy word.

Blood, we were talking about blood.

Because if you're killed by carbon monoxide, there is such a powerful chemical reaction in your blood as the oxygen is muscled out of the blood stream that the blood cells are turned a bright, cherry red.

So it's not using oxygen and really these cells, we call them cells and there are many senses of the word, but they don't really have mitochondria, they also don't have nucleus.

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

450 out, and she's tachy in the 130s.

Thrombosis is the process of a thrombus forming.

My blood is your blood.

His blood is your blood.
