Resource summary

Page 1

Capillaries Supply all cells with their requirements. Take away waste products. Very thin, only one cell thick walls. Very narrow lumen, just wide enough for a red blood cell to pass through. No valves. Thin walls and narrow lumen bring blood into close contact with body tissue, allowing diffusion of materials between capillary and surrounding tissues.
