n. the transport of matter out of a living cell by the movement of a filled vacuole to the cell membrane and the extrusion of its contents (disting. from endocytosis). [1960–65] ex`o•cy•tot′ic (-ˈtɒt ɪk) ex`o•cyt′ic (-ˈsɪt ɪk) adj. exocytosisenUK

exocytosis [ek″so-si-to´sis] 1. the discharge from a cell of particles that are too large to diffuse through the wall; the opposite of endocytosis.2. the aggregation of migrating leukocytes in the epidermis as part of the response" >inflammatory response.ex·o·cy·to·sis (ek'sō-sī-to'sis), 1. The appearance of migrating inflammatory cells in the epidermis. 2. The process whereby secretory granules or droplets are released from a cell; the membrane around the granule fuses with the cell membrane, which ruptures, and the secretion is discharged.
