If your body was the size of the Atlantic ocean, your red blood cells would be the size of the Titanic

Let that sink in

I'm teaching my white blood cells math and my red blood cells computer science

Once they become STEM cells I am hoping to regrow a finger.

Two red blood cells are talking to two platelets...

One red blood cell says "I heard you two finally tied the clot!"

The other says "Coagulations!"

TIL Type O blood was actually meant to be Type Zero blood, due to lack of glycoproteins in the red blood cells. It was misread as type "O".

I guess you can call it a typo.

What do you call the iron-stealing, oxygen-depleting metalloproteins that lurk in the red blood cells of all vertebrates?

Hemogoblins.
