We had a creative writing project in anatomy and physiology (for some reason) where we had to personify the immune system in some creative manner. I wrote a not so short story (was aiming for a page, ended up with two and a half), but I wanted to properly and fully design the cell creatures I'd thought up for the purpose of the story.

So I drew them! We have:

Influenza Type-A

A macrophage

A helper T-cell

A killer T-cell

And a B-cell with antibodies

My thought was that they should look pretty alien because cells already look kinda wack. It was quite hard to come up with a creature design for several amorphous blobs.

Pretty random? Yeah, but hey content.
