Identify one function of the central nervous system.

The central nervous system (CNS) plays a crucial role in processing information and coordinating responses within the body. It consists of the brain and spinal cord, which are responsible for interpreting sensory input, making decisions based on that information, and sending signals to various parts of the body to elicit appropriate responses. For example, when you touch something hot, sensory receptors send information to the brain, which processes the sensation and signals the body to withdraw your hand quickly. This capability allows the CNS to serve as the main control center for bodily functions and reactions, influencing everything from voluntary movements to reflexes.

The other options describe functions that are primarily associated with other systems in the body. Secretion of hormones is primarily managed by the endocrine system, which consists of glands that release hormones into the bloodstream to regulate various bodily functions. Regulation of digestive processes is largely the responsibility of the gastrointestinal system and its associated nervous system, which operates independently of the CNS through the enteric nervous system. Lastly, facilitating gas exchange in the lungs is a function of the respiratory system, particularly involving the alveoli and capillaries, rather than the central nervous system itself. Thus, the correct identification of the CNS's function emphasizes its pivotal role in information processing and coordination of bodily responses
