The process you are referring to is called vesicle budding. This occurs when a cell membrane invaginates, forming a vesicle that eventually pinches off to transport cellular material within or out of the cell. This process is essential for cell communication, nutrient uptake, and intracellular trafficking.
The endoplasmic reticulum (ER) processes and modifies secretory proteins, ensuring they are properly folded and assembled. Once this is complete, the proteins are packaged into transport vesicles that bud off from the ER. These vesicles then move to the Golgi apparatus for further processing, sorting, and eventual secretion to their final destinations. This process is crucial for maintaining cellular function and communication.

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.
Vesicles pinch off of the endoplasmic reticulum (ER), Golgi apparatus, and plasma membrane. These vesicles transport molecules such as proteins and lipids to various locations within the cell or for secretion outside the cell.

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.

To deliver secretory products to the extracellular spaces.
They mostly secrete proteins...
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.
