Duct

A nonmetallic or metallic tube for housing wires or cables, may be underground or embedded in concrete floor slabs; a duct usually fabricated of metal, used to transfer air from one location to another.

(geophysics)

(mechanical engineering)
A fluid flow passage which may range from a few inches in diameter to many feet in rectangular cross section, usually constructed of galvanized steel, aluminum, or copper, through which air flows in a ventilation system or to a compressor, supercharger, or other equipment at speeds ranging to thousands of feet per minute.

1. ,See air duct.
2. In electric systems, a metallic or nonmetallic tube, (usually circular, oval, rectangular, or octagonal) for housing wires or cables; may be underground or embedded in concrete floor slabs.

duct

(13) Recently, Ohtomo et al (14) found SOX10 was expressed in both luminal and abluminal cells of intercalated ducts of normal human major salivary glands.
The tumors with frequent and high SOX10 expression are acinic cell carcinoma, adenoid cystic carcinoma, epithelial-myoepithelial carcinoma, myoepithelial carcinoma, and pleomorphic adenoma, which presumably show similarities to acini and intercalated ducts. The tumors with no SOX10 expression are salivary duct carcinoma, mucoepidermoid carcinoma, squamous cell carcinoma, oncocytic carcinoma, oncocytoma, and Warthin tumor, which are usually thought to resemble striated and excretory ducts.
DOG1 expression was seen in normal serous acini (apical membranous staining pattern), mucous acini (apical membranous staining pattern), and distal intercalated ducts (apical staining).
As the intercalated ducts are less in number most of the terminal alveoli are often quite elongated and open directly into the larger interlobular ducts at the periphery of the lobule.
This measured square was used for counting the number of intercalated ducts, striated ducts, acini and demilunes.
Diagnosis and ultrastructure of the tubular carcinoma of salivary gland ducts: epithelial-myoepithelial carcinoma of the intercalated ducts [in German].
The acini drain into the intercalated ducts, composed of a single layer of cuboid epithelium.
Intercalated ducts, striated ducts and interlobular ducts were observed in this gland.
There are intercalated ducts with cubical epithelium connecting the acini with the striated ducts.
Acinic cell adenocarcinomas arise from pluripotential reserve or stem cells normally found at the acinar-intercalated duct junctions or in the intercalated ducts proper of mature salivary glands.[2]
