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

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

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.

Baby's blood.

Some of these experiments are more fi than sci.

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.

Come on, fucking fastball.

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

Your blood count's dropping.
