<span>Some liver cells ingest bacteria, a function probably accomplished by</span>phagocytosis.
Phagocytosis refers to the intake of very large particles by cells. In an organism's immune system, phagocytosis is used to remove pathogens and cell debris.
When liquids boil the particles must have sufficient energy to break away from the liquid and to diffuse through the surrounding air particles. As these particles cool down and lose energy they will condense and turn back to liquid.
