A brief glimpse into REALJOB; today I'm working on a presentation that I'll be giving on a teaching course for advanced nursing practice about blood tests and result interpretation. Thought you might like to see one of my absolute favourite you tube videos ever!
In this clip, a white blood cell is moving along the chemical signal path that's left by a bacterium (small black figure 8 shaped blob that's running away), moving between red blood cells (the big round blobs that look a little bit spiky). When it catches up, it basically stretches out a couple of arms, wraps them around the bacterium and engulfs it. The cell will then unleash chemical warfare on the engulfed bacterium, dissolving it.
Science is awesome.
