30. Draw & label these blood vessels
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

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