Vesicle \Ves"i*cle\, n. [L. vesicula, dim. of vesica a bladder, blister; akin to Skr. vasti bladder: cf. F. v['e]sicule.] A bladderlike vessel; a membranous cavity; a cyst; a cell. Specifically:
(Bot.) A small bladderlike body in the substance of vegetable, or upon the surface of a leaf.
(Med.) A small, and more or less circular, elevation of the cuticle, containing a clear watery fluid.
(Anat.) A cavity or sac, especially one filled with fluid; as, the umbilical vesicle.
(Zo["o]l.) A small convex hollow prominence on the surface of a shell or a coral.
(Geol.) A small cavity, nearly spherical in form, and usually of the size of a pea or smaller, such as are common in some volcanic rocks. They are produced by the liberation of watery vapor in the molten mass.
Douglas Harper's Etymology Dictionary
"small, bladder-like structure," early 15c., from Middle French vesicule, from Latin vesicula "little blister," diminutive of vesica "bladder, blister" (see ventral).

Wikipedia
In cell biology, a vesicle is a small structure within a cell, consisting of fluid enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion ( exocytosis), uptake ( phagocytosis and endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes. If there is only one phospholipid bilayer, they are called unilamellar liposome vesicles; otherwise they are called multilamellar. The membrane enclosing the vesicle is also a lamellar phase, similar to that of the plasma membrane, and vesicles can fuse with the plasma membrane to release their contents outside the cell. Vesicles can also fuse with other organelles within the cell.
Vesicles perform a variety of functions. Because it is separated from the cytosol, the inside of the vesicle can be made to be different from the cytosolic environment. For this reason, vesicles are a basic tool used by the cell for organizing cellular substances. Vesicles are involved in metabolism, transport, buoyancy control, and enzyme storage. They can also act as chemical reaction chambers.
The 2013 Nobel Prize in Physiology or Medicine was shared by James Rothman, Randy Schekman, and Thomas Südhof for their roles (building upon earlier research, some of it by their mentors) on the makeup and function of cell vesicles, especially in yeasts and in humans, including information on each vesicle's parts and how they are assembled. When cell vesicles, which help maintain a balance or equilibrium inside and outside of the blood vessels and cells (between the intravascular and extravascular spaces and the intracellular and extracellular spaces, respectively), malfunction, potentially serious and often fatal conditions are the result. The dysfunction is thought to contribute to Alzheimer's disease, diabetes, some hard-to-treat cases of epilepsy, some cancers and immunological disorders, and certain neurovascular conditions. These are likely either caused, influenced, or made worse, by the disorders of the cell vesicles.
