An anatomical canal is a passage or tube within the body that connects two different parts of the body. The term 'anatomical canal' is derived from the Latin word 'canalis, ' which means 'CHANNEL.' The most common example of an anatomical canal is the ITER, which is a four-letter Latin word meaning 'PATHWAY' or 'JOURNEY.' The ITER is a passageway between the heart and lungs, allowing oxygenated blood to travel from the lungs to the heart.
