The cytoplasmic vesicles mediate vesicular transport among the organelles of secretory and endocytic systems. These transport vesicles are classified by the identity of the protein coat used in their formation and also by the cargo they contain, e.g. clathrin-, COPI-, and COPII-coated vesicles, synaptic vesicles, secretory vesicles, phagosomes, etc.
