lymphatic duct (right)
a vessel draining lymph from the cranial right side of the body, receiving lymph from the right subclavian, jugular and mediastinal trunks when those vessels do not open independently into the right brachiocephalic vein.

pancreatic duct
the main excretory duct of the pancreas, which usually opens with the bile duct on the major duodenal papilla; may be a single duct, or two ducts which join, or two independent ducts opening into opposite sides of the intestine. See also bile duct. Called also Wirsung's duct.
papillary d's (kidney)
the straight excretory or collecting portions of the renal tubules, which descend through the renal medulla to a renal papilla or renal crest.

It composed mostly of pale white connective tissues, interlobular septa with scattered lobules containing small dark cross cuts of many intralobular ducts.
As demonstrated in the histopathological appearance of figure 10, it shows the presence of mostly pale white connective tissue interlobular septa with scattered lobules containing small dark cross cuts of many intralobular duct with intact alveoli.
The secretions of the acini pass through the intralobular ducts which include the intercalated and striated ducts and then interlobular or excretory ducts and ultimately into one or more main ducts which discharge saliva into the oral cavity1.
Both segments of the intralobular ducts are poorly developed, and intercalated ducts are virtually absent.
The fibroinflammatory process extends to the interlobular and intralobular ducts as well as to the acinar component, which progressively display atrophy and are replaced by fibrosis (Figure 4).
They are purely serous glands and excretory intralobular ducts, intercalated and particularly striated ones, are very numerous.
