cool hand angiography

An angiography is the imaging of blood vessels, usually by injecting a radio-opaque fluid into the veins and then x-raying them. This patient has a finger angioma, where a benign tumor has developed and resulted in an unusual clogging of vessels.

I think my favorite part is the delicate delta of veins under the thumbnail though.

Just a nice GIF of a white blood cell mercilessly pursuing an invading bacteria through a field of red blood cells.

Basically, each of the pathogens (bacteria) let off a chemical “scent” that the white blood cell is attracted to and chases. Similarly, the white blood cell has a chemical marker that the bacteria can pick up on, but instead it moves away.
