An assembly or meeting with all members present.

(Anatomy) A tubular bodily canal or passage, especially one for carrying a glandular secretion

A condition, space, or enclosure in which air or other gas is at a pressure greater than that of the outside atmosphere.

A tube or pipe for enclosing electrical cables or wires.

The condition of being full; fullness.

To channel through a duct

A space completely filled with matter.

To supply with ducts.

A space lying above the ceiling in a building but below the next floor, especially one allowing movement of air between parts of the building.

A pipe, tube or canal which carries gas or liquid from one place to another

(physics) A space that is completely filled with matter.

An enclosure or channel for electrical cable runs, telephone cables, or other conductors

(figuratively) A state of fullness, a great quantity (of something).

(anatomy) a vessel for conveying lymph or glandular secretions such as tears or bile

Any tube or canal by which a fluid or other substance is conducted or conveyed.
