Which body system is responsible for processing sound information?

The nervous system is responsible for processing sound information because it includes the auditory system, which consists of the ears and the pathways that transmit sound signals to the brain. When sound waves enter the ear, they are converted into electrical signals by the hair cells in the cochlea. These signals are then sent via the auditory nerve to the brain, specifically to areas like the auditory cortex, where they are interpreted as sound.

The other systems listed do not play a direct role in processing sound. The respiratory system is primarily involved in breathing and gas exchange, the circulatory system transports blood and nutrients throughout the body, and the digestive system processes food and absorbs nutrients. Thus, while all these systems are important for overall body function, only the nervous system is directly involved in managing sound information.
