exocytosis
Vesicle membrane fusion
Exocytosis is the process by which cells release substances to the outside.
A membrane-bound sac inside the cell fuses with the outer cell membrane, expelling its contents—hormones, neurotransmitters, waste products.
The reverse process, bringing material in, is endocytosis.
