And the red region is a slice into a red blood cell.

You are now about the size of a red blood cell.

A red blood cell is to big to be considered nano.

Blood... so red...

The blood ran red.

like red blood cells.

At this size the red blood cell is one thousand times bigger than you are.

So just remember, red blood cell don't really need oxygen they're simply carrying it around.

The blood was bright red.

Every red blood cell of your body right now has these hourglass shaped pores called aquaporins.

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

This is a white blood cell.

The white blood cell count plummets.

Don't forget... the red cell phone.

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

Yeah, his blood wasn't even red.

Don't forget... the red cell phone's important.

DONATE YOUR BLOOD TO THE RED CROSS

I'm not sure... the red cell phone's important.

The rhinovirus is only about thirty nanometres across and is nearly impossible to see next to the red blood cell.

The Red Cross supplied the hospital with blood.

Its blood is red. It must have hemoglobin.

The red cell phone ? What are you talking about?

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.

Freitas has a design for a robotic white blood cell.

Red, that's a bowl of tiny cell phones. phone ringing

Let's make this grid cell red over here as well.

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

They are actually red that's what gives blood its color.

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

So, the probability of seeing red at the red grid cell is 0.8, and the probability of seeing green at the green cell is also 0.8.

It's the layer all the red blood cells are bumping up against.

Let's say the robot sees red, and as before, the probability of seeing red in Cell A is 0.9.

Blood, blood, blood.

So here's an image of red blood cells, and now we can actually map where the hemozoin and where the malaria parasites are inside those red blood cells.

What are now the posterior probabilities that the robot is at the red cell given that it just saw red and conversely what's the probability that it's at the green cell even though it saw red.

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.

We see red again. That makes this cell over here the most likely.

There's one nano engineered device that cures type 1 diabetes. It's blood cell sized.

Blood, blood, blood. So much.

Lab says some blood evidence found at my ci crime scene is almost human... except there's no red blood cells present.

What now fits in our pockets would fit in a blood cell in 25 years.

Blood for blood.

Your steely blue was tinted with gore, ran red with the blush of fresh blood.

So what you see in the picture there is a cell with a hormone receptor in red punching through the edge of the cell.
