Type of Cells


Several major types of
Absorptive Cells
Absorptive cells often occur as continuous sheet on surfaces where material is transported to the cells. For example, the single layer of epithelial cells lining the surface of the small intestines selectively absorbs, food molecules from the gut into the
Secretor Cells
Secretor cells produce products that are subsequently deposited in either the bloodstream or a special duct to an organ, where they are used. The pancreas and pituitary are glands that have large number of secretor cells. Protein and other cell products are synthesized throughout the cytoplasm and transported to the Golgi apparatus, where they are packed into a membrane bonded vesicle that come to a cell's surface and discharge the secretion outside the cell.
