magine you are a macrophage: a merciless white blood cell that stalks, amoeba-like, through the tissues of the body, looking for pathogens, dead and dying cells, and other undesirables. When you encounter one of these, your task is not just to destroy it, but to devour it whole. (Chomp!)This complete annihilation may seem a bit over the top, but it serves two useful purposes. First, it recovers valuable macromolecules for the body’s use. Second, in the case of foreign pathogens, it allows the macrophage to present fragments of the pathogen on its surface. This display alerts other immune cells that the pathogen is present and triggers an immune response.

Bulk transport:-
Endocytosis and exocytosis. Phagocytosis, pinocytosis, and receptor-mediated endocytosis.
