Here's how it works:
* Engulfment: The cell membrane surrounds the particle, forming a pocket.
* Vesicle Formation: The pocket pinches off, creating a vesicle (a small membrane-bound sac) containing the particle.
* Digestion: The vesicle fuses with lysosomes, which contain enzymes that break down the particle.
So, phagocytosis is an endocytotic process, meaning it brings things into the cell, not out.
