Capillaries
Very
thin-walled (one cell thick).
Site for the exchange of materials between the blood &
body tissue (cells). (where Hemo does his work)
Arterioles
and venules are connected by capillaries.
1) Artery (arterioles)
2) Vein (venule)
3) Capillary
Draw & label these blood vessels

Capillary cross-section
NUCLEUS
• Very thin-walled
(one cell passes
through at a time.)
This is where materials
are exchanged
between the blood and
the body cells.
