Exocytosis is the process by which cells transport materials from the inside of the cell to the exterior environment. This involves the fusion of vesicles with the plasma membrane, and the subsequent release of the vesicle contents to the outside of the cell. Exocytosis is used by cells to secrete hormones, neurotransmitters, and other important molecules.
