membrane bound structures that are responsible for the transportation of molecules in and out of a cell
They are known as Cytoplasmic Vesicles, such as lysosomes and peroxisomes. Another separate class is the Organelle, such as the Mitochondria and the Nucleus.
The rough endoplasmic reticulum makes proteins. The Golgi acts as the shipping department if the cell is understood to be a protein factory.
The Golgi body
In cell biology, a vesicle is when the cell membrane folds in on itself, enclosing the item in a sphere. Vesicles are transport and storage structures in a cell's cytoplasm. Source- science textbook
The movement of materials out of the cell by using a vacuole or vesicle is generally referred to as exocytosis.

To deliver secretory products to the extracellular spaces.
Vesicles perform many functions through complex mechanisms that can involve many aspects of cell regulation. Secretory vesicles in particular are specialized vesicles formed in the trans-golgi apparatus for releasing a product (such as molecule or protein) outside the cell. Secretory vesicles are used for exocytosis. Mast cells use secretory vesicles to release histamine which is a molecule involved immune response. Neurotransmitters can also be transmitted in secretory vesicles from nerve cells.

They are made by golgi bodies.Their function is transportation.
Secretory vesicles can form from the Golgi apparatus, which packages proteins and molecules for secretion. These vesicles can also be formed from endosomes that have internalized molecules or from specialized secretory cells in the body. Once formed, secretory vesicles move towards the cell membrane for exocytosis to release their contents outside the cell.

They mostly secrete proteins...
Chromogranin A is a type of secretory protein, found in the vesicles of neurons and endocrine cells. An abnormality can mess with its function in helping control the modulating proteins.
Transport vesicles Transport vesicles can move molecules between locations inside the cell, e.g., proteins from the rough endoplasmic reticulum to the Golgi apparatus. Membrane-bound and secreted proteins are made on ribosomes found in the rough endoplasmic reticulum. Most of these proteins mature in the Golgi apparatus before going to their final destination which may be to lysosomes, peroxisomes, or outside of the cell. These proteins travel within the cell inside of transport vesicles. Secretory vesicles Secretory vesicles contain materials that are to be excreted from the cell. Cells have many reasons to excrete materials. One reason is to dispose of wastes. Another reason is tied to the function of the cell. Within a larger organism, some cells are specialized to produce certain chemicals. These chemicals are stored in secretory vesicles and released when needed.
Golgi bodies
The Golgi apparatus receives transport vesicles from the endoplasmic reticulum and processes them. It modifies, sorts, and packages proteins into lysosomes and secretory vesicles for transport to different parts of the cell or outside the cell.
