Chemotaxis
Neutrophils are White blood cells that hunt and kill
bacteria, in this spread a neutrophil is seen in the
midst of red blood cells a staphilococos aureus
bacteria has been added the bacteria releases a
chemo attractant that is sensed by the neutrophil.
The neutrophil becomes polarized and starts chasing
the bacteria, the bacteria bounced around by thermal
energy moves in a random path seeming to avoid its
predator, eventually the neutrophil catches up with
the bacteria and engulfs it by fagocytosis.
