Which function is NOT associated with the nervous system?

The exchange of gases is primarily a function of the respiratory and circulatory systems, rather than the nervous system. The respiratory system is responsible for facilitating the exchange of oxygen and carbon dioxide between the body and the environment, while the circulatory system transports these gases throughout the body. In contrast, the nervous system plays a crucial role in coordinating muscle movements, processing sensory information, and transmitting nerve impulses, all of which are essential for responding to external stimuli and controlling bodily functions.
