A duct is a tube or channel that carries something — usually air, water, or a body fluid — from one place to another. In houses, air ducts carry heated or cooled air around the building. In the body, tear ducts carry tears, and other ducts carry things like milk or fluids. It's a fairly technical, practical word, common in engineering, biology, and home repair talk.
