Solution

Diapedesis is the migration of blood cells, especially WBCs (leucocytes), through the intact walls of blood vessels into the surrounding tissue to fight foreign agents.
The white blood cells are very small in size and are capable of amoeboid movement by changing the body shape according to the requirement. This property of WBC helps them to squeeze through the walls of blood vessels.
