The answer to the crossword for the term 'organ with a canal' is EAR, which stands for the organ of hearing. The EAR is a complex organ that is responsible for hearing and balance. It consists of three parts: the outer EAR, the middle EAR, and the inner EAR. The outer EAR collects sound waves and directs them into the EAR canal, which leads to the middle EAR. The middle EAR contains three tiny bones that transmit the sound waves to the inner EAR. The inner EAR contains the cochlea, which converts the sound waves into nerve signals that are sent to the brain.
