Endocytosis and Exocytosis Processes

Endocytosis

Process of taking in materials via vesicles.

Exocytosis

Process of expelling materials via vesicles.

Pinocytosis

Cell drinking; intake of small droplets.

Phagocytosis

Cell eating; intake of large particles.

Receptor-Mediated Endocytosis

Intake of specific molecules via receptor binding.

E.C.F.

Extracellular fluid surrounding cells.

Vesicles

Membrane-bound sacs transporting materials in cells.

Specialized Cells

Cells that perform unique functions, like macrophages.

Cholesterol Intake

Specific uptake of cholesterol via receptor-mediated endocytosis.

Secretory Cells

Cells that release substances, like pancreas cells.

Macrophages

Immune cells that perform phagocytosis.

Amoeba

Single-celled organism that uses phagocytosis.
