Fig. 4.

Diameters and branching angles of microvessels at arteriole–capillary intersections with potential arrest of cells/beads. A Diameter of arterioles versus diameter of side branches (most of them are capillaries) at arteriole–capillary intersections. B Diameter of arterioles versus branching angle θ between arteriole and side branch. Empty green circles: total arteriole–capillary (a–c) intersections examined in five rats injected with beads; yellow filled circles: intersections with arrested beads. Empty green triangles: total arteriole–capillary intersections examined in six rats injected with tumor cells; red filled triangles: intersections with arrested cells
