Keeping Hazardous Substances out of the Body
The cells at the bottom are alive and dividing.
Cells at the surface are dead and eventually flake off.
A = outer layer of dead skin cells
B = growth layer of skin
C = connective tissue
D = sense organ

White blood cells are involved with protecting us from invaders.
Pt = platelets (make blood clot)
PL = plasma (fluid)
The white blood cell is the larger cell.
The dark smaller cells are the bacteria.
This 3d image shows the white blood cell and its pseudopods beginning to engulf the rod shaped bacterium.
Tsetse flies carry trypanosomiasis (sleeping sickness).
Blood is poisoned, lymph nodes and the brain’s covering swell.
The large brownish spot with the dark markings is a white blood cell.
