In humans, all white blood cells are referred to as amoeboid cells.
They tend to have diapedesis, or extending pseudopodia like expansion via holes, to escape the endothelium lining present in blood arteries.
They encapsulate the bacteria and cellular detritus in the same way that an amoeba encloses its food particles.
Final Answer:
In humans WBCs are amoeba-like cells which compress through walls of the blood capillaries.
