Understand that endocytosis is the process by which cells internalize substances from their external environment by engulfing them in vesicles.
Recognize that there are different types of endocytosis based on the size and nature of the material being internalized.
Identify that phagocytosis specifically refers to the engulfment of large particles such as bacteria or cell debris into large vesicles called phagosomes.
Note that pinocytosis involves the uptake of fluids and small molecules, while clathrin-mediated and caveolae-mediated endocytosis are specialized pathways for smaller molecules and receptor-mediated uptake.
Conclude that the term describing the engulfment of large particles into internal vesicles is phagocytosis.
