Changes allowing cells to perform specialized roles

Can differentiate into several different cell types

Red blood cell formation from bone marrow stem cells

Increases surface area for gas exchange

They lack a nucleus

First line of cellular defense at infection sites

Process neutrophils use to destroy pathogens
