What is a "canal"?
A canal refers to a tubular passageway or channel that exists within various anatomical structures. Canals serve important functions in the body, such as facilitating the passage of fluids, substances, or structures. They can be found in different regions, including the ears (eustachian canal), the spinal cord (central canal), and the digestive system (intestinal canal). Canals play a crucial role in maintaining the proper functioning of the body by allowing the transportation of essential substances, providing pathways for nerve fibers, or facilitating the drainage of fluids.
