How do white blood cells get into the tissues or other body cavities. Some WBCs are even larger than rbcs, and I dont see how they would be able to squeeze through the spaces between epithelial cells lining capillary walls.

Lymph capillaries are slightly larger than their counterpart capillaries of the vascular system.
