Q1) the duct are lined by statified cubiodal epithelium . they discharge their contents onto the surface of skin via coilled secretory duct. the ducts opens out onto epidermal ridges at sweat pores.
Q2)the Holocrine term used to classified the mode of secreation in exocrine glands in the study of histolgy . it is produced by in cytoplasm of the cell and released by cell rupture of the plasama membraine, which destroy the cell and result in secreation of the product into lumen
Q3) Acinar cells produces digestive enzymes amylases , lipsa and peptidases. pancreatic peptidases are produced as inactive zymogens that are only activeted after they reached the duodenum.
