by splinter
Damaged mast
cells release
histamine.
Histamine
diffuses
into the
capillaries.

Bacteria
Phagocytes
move into
infected tissue.
Activated complement
proteins attract
phagocytes.
Histamine causes the
capillaries to dilate
and become leaky.

Phagocytes
engulf bacteria
and dead cells.
Dead
cells
Histamine and
complement
signaling cease,
phagocytes are no
longer attracted, and
the tissue returns to
normal.
