Final answer:
Exocytosis is the process of a cell releasing materials, which can then reenter the cell through endocytosis.

Exocytosis is the process by which a cell releases materials to its exterior. These materials can reenter the cell through a process known as endocytosis. Endocytosis is the opposite of exocytosis, where materials are taken into the cell by enclosing them in a membrane-bound vesicle.
