The primary function of the brain is to act as the control center for the body, regulating and coordinating bodily functions, thoughts, emotions, and behaviors. It processes sensory information received from the environment, enabling perception and response. The brain is responsible for higher cognitive functions such as reasoning, problem-solving, memory, and language. Additionally, it regulates vital functions such as heartbeat, breathing, and digestion. Divided into various regions, each with specialized roles, the brain integrates complex neural networks to maintain homeostasis and allow adaptive responses to changing conditions in the environment.
