Correctly match the different functional modes of exocrine gland secretion.
Definition 1 - Secretions released from cell in secretory vesicles via exocytosis. Therefore the cells remain intact. Merocrine Definition 2 - Secretory product accumulates in cytosol. As it matures, the cell membrane ruptures releasing the secretory contents. With the rupture of the cell membrane, this cell dies and gets replaced by a new cell. Holocrine Definition 3 - Secretory product accumulates in cell apical region. Then, that portion of the cell pinches off from the rest of the cell to release the secretion. Therefore, only the apical part of the cell gets removed, but cells do not die. Apocrine
