How are capillaries adapted for their function within the body?

Capillaries have walls only one endothelial cell thick, meaning their walls are very thin. This makes them well adapted for gas exchange, as substances only have to diffuse over a short distance. Additionally, there are many capillaries within a capillary bed. This also increases the surface area available for gas exchange, making exchange more efficient.
