A duct is a tube, conduit, or channel that is specifically designed to transport fluids, air, or gases. It is commonly made of various materials such as metal, plastic, or fiberglass, depending on its intended use and environment.
Ducts are found in various systems and structures, serving different purposes depending on the context. In heating, ventilation, and air conditioning (HVAC) systems, ducts are utilized to distribute conditioned air from a central unit to different rooms or areas within a building, ensuring proper temperature regulation. Similarly, ducts are also employed in exhaust systems to remove stale air, unwanted odors, or pollutants from a space.
In the human body, a duct refers to a passage or tube that carries bodily fluids, secretions, or excretions. For instance, in the digestive system, the bile duct carries bile from the liver to the small intestine, aiding in the digestion and absorption of fats. In the urinary system, the ureter is a duct that transports urine from the kidneys to the urinary bladder for elimination.
Overall, a duct acts as a pathway or conduit for the efficient transportation of fluids, air, or gases, allowing them to flow from one point to another within a specific system or structure.
