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 Saccone Powerpoint

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 RBC Capillary Saccone Powerpoint
