(15 of 38) Excretory Ducts Extending across the central part of the image is a wide septum of connective tissue containing a nerve (A) and several secretory ducts (B). Secretory ducts empty into excretory ducts (C). Histo-logically, excretory ducts vary in appearance from simple columnar to pseudostratified columnar to stratified squamous. The cells lining the excretory duct in the center of the field appear to be pseudostratified columnar. Most excretory ducts are interlobular in position. |
