Secretory vesicles
Secretory vesicles are small bubble-like structures within cells that transport and release substances, such as hormones or neurotransmitters. When a cell needs to send out these chemicals, secretory vesicles gather them and move to the cell membrane. Once they reach the membrane, the vesicles merge with it, releasing their contents outside the cell. This process is essential for communication between cells and plays a crucial role in regulating various bodily functions, such as mood, metabolism, and immune responses. Essentially, secretory vesicles help cells share important messages and materials with each other and their surroundings.
