Fahraeus-Lindqvist effect

Fahraeus-Lindqvist effect
blood viscosity is lower in small vessels (diameter less than 1.5 mm) than in large vessels, the viscosity in capillaries being less than half that in large vessels; the effect is due to red cells moving together in single file through the small vessels.
