[Characteristics of thrombus formation in arterioles and venules]

The model of laser-induced thrombosis revealed a greater thromboresistance in arterioles rather than in venules of the rat small intestine mesentery, which accounts for a less frequent thrombosis and a lesser size of thrombus along the blood flow direction, whereas their greater thrombogenic potential accounts for a faster growth of thrombus and a shorter time of the primary hemostasis.
